Arkham Horror LCG: What to Buy After Revised Core in 2026

The clean order is Revised Core, Dunwich Campaign, Dunwich Investigator, then Carcosa Campaign. Replay the Core before opening Dunwich. The first run teaches actions and tests; the second teaches consequences, resigning, deck weaknesses, and why a campaign can continue after a bad resolution. If your table still wants another case after that replay, it has earned a full campaign.

Buy the two Dunwich boxes for different reasons. The Dunwich Legacy Campaign Expansion contains the complete eight-scenario story: missing Miskatonic professors, the Clover Club, a museum break-in, a train that becomes a rules lesson at speed, the village of Dunwich, and a final collision with forces outside ordinary space. The Dunwich Legacy Investigator Expansion contains five investigators and the player cards from that cycle. It contains no campaign.

Carcosa is the next story step because the campaign uses uncertainty as part of its drama without asking a beginner to absorb the heaviest later-campaign administration. Its cursed production of The King in Yellow moves from an Arkham theatre through interviews, obsession, travel, and the question of whether the investigators can trust their own account. It feels like the moment Arkham stops being a clever card system and becomes a campaign people remember years later.

The official Learn to Play book lists 245 player cards, 111 scenario cards, chaos tokens, resource, damage, horror, clue and doom tokens, five investigator mini-cards, and the supporting campaign material. It supports one to four players from one box. The Core's Night of the Zealot story is intentionally compact: The Gathering teaches the room, The Midnight Masks opens Arkham into a timed search, and The Devourer Below demonstrates that a campaign finale is allowed to be cruel.

Use the recommended decks for the first session. The manual provides starter lists for Roland, Daisy, 'Skids,' Agnes, and Wendy, plus role tips. Do not interpret the finale as a product review. The Core campaign is a tutorial with teeth, not a representative eight-scenario arc. You are ready to expand when the group can run Mythos, Investigation, Enemy, and Upkeep without rebuilding the rules every phase; when each player can state a primary job; and when the group wants to know what happens after a scenario rather than merely whether it won.

Robert's practical test is faster: can the group reset the encounter sets, update the campaign log, and name next week's date before the snacks disappear? If yes, buy a campaign. If no, replay the Core or use the interactive setup trainer until the physical table stops feeling like the first enemy.

Read the final noun printed on the modern box. A Campaign Expansion contains the scenario, encounter, act, agenda, location, story, and campaign material for that arc. It requires a compatible Core and legal investigator decks. An Investigator Expansion contains investigators and player cards for deck construction. It adds no scenarios. You can play Dunwich investigators in Carcosa, bring Edge of the Earth cards to Dunwich, or use Revised Core investigators in Hemlock Vale. Matching titles are not a requirement.

The retired model used one Deluxe Expansion plus six separate Mythos Packs to distribute one cycle. Those old products are mechanically usable, but they are dangerous first purchases because the Deluxe box is only the opening fragment. One missing pack can strand the whole campaign. The modern Dunwich Campaign box already includes The Essex County Express; a newcomer does not need the separate Essex Mythos Pack.

One community explanation remains the cleanest practical shorthand: Campaign Expansion means roughly a full campaign; Investigator Expansion means investigators and player cards. Puzzlewick adds the cart check: the exact product title, SKU, cover noun, and Amazon product page must all agree before the button earns a place here.

Dunwich begins with Dr. Henry Armitage asking the investigators to find two missing colleagues. The opening fork lets the group visit Miskatonic University or the Clover Club first, which immediately teaches that campaign order can alter later setup and available help. The route moves through an after-hours museum, the celebrated moving-train structure of The Essex County Express, rural Dunwich, invisible threats, sorcerous gates, and the void beyond. It is pulpier and mechanically plainer than later campaigns, which is exactly why it works as the first long course.

The official campaign guide identifies eight scenarios and provides a campaign log, chaos-bag changes, story assets, and scenario-specific location diagrams. The train layout in the manual is a perfect example of Arkham's physical storytelling: locations connect left and right as cars disappear behind you. It teaches movement, urgency, and scenario text without adding a second campaign-wide subsystem.

Dunwich does show its age. Some scenarios are short, one can punish particular deck shapes, and the finale is less theatrical than modern campaigns. Buy it for fundamentals and the feeling of a classic Arkham file, not because release order is sacred. If the modern Campaign Expansion is scarce or inflated, skip directly to another complete campaign at a sane price. Do not reconstruct Dunwich from old packs out of obligation.

Yes, when you can find the exact modern box at a sensible price. The Dunwich Investigator Expansion adds Zoey Samaras, Rex Murphy, Jenny Barnes, Jim Culver, and 'Ashcan' Pete, plus the cycle's player cards. Its investigators can use a small amount of off-class level-zero material, which makes a small collection feel broader. Its card pool also contains foundational economy, clue, combat, skill, and deck-consistency tools that continue to appear in community recommendations.

Community language often calls Dunwich 'Core, part two.' That is not an official product claim, but it captures why the box works early: it gives most classes practical cards rather than asking a new collection to support a narrow late-cycle archetype. One recent owner thread summarized the case as cards 'that every deck uses.' The important caveat is that Revised Core alone is already playable. This box adds consistency and options; it is not an admission ticket to the campaign.

If Dunwich Investigator is scarce, Edge of the Earth Investigator Expansion is the best substitution. Its multi-class cards can enter a deck through either printed class, so a single purchase touches many investigators. The official insert devotes a page to that multi-class rule. Edge can introduce more powerful and more complex options, but it remains a better small-library expansion than buying a random set purely because it is available.

Carcosa begins at a performance of The King in Yellow. The investigators leave the Ward Theatre with questions about the play, its cast, and the events surrounding it; the trail then moves through Arkham society, an asylum, Paris, catacombs, Mont Saint-Michel, and places where the distinction between conviction and doubt becomes campaign material. The guide tracks what the group believes, not merely what it defeats.

That structure is why Carcosa keeps winning broad recommendations. A March 2026 campaign thread gave the concise verdict: 'I would get Carcosa if you're only picking one.' The useful translation is not that every group must rank it first. It is that Carcosa offers a large story payoff without making the buyer study the densest campaign machinery first. Dunwich teaches the syntax; Carcosa shows what the language can do.

The exact-product problem is unusually important here. Carcosa has old Deluxe boxes, individual Mythos Packs, a modern Investigator Expansion, a modern Campaign Expansion, and Amazon listings whose variant titles can become muddled. Our primary Amazon recommendation is the direct two-box bundle because the product image visibly contains the modern Investigator and Campaign boxes. If you buy only the Campaign Expansion, verify that the page and cover both say Campaign Expansion before checkout.

Choose by the kind of night your group wants, then let availability break ties. The Feast of Hemlock Vale sends Dr. Rosa Marquez and the investigators to an island preparing for a festival while mutated wildlife and an unnatural presence close in. Its official guide contains eight scenarios, but a campaign plays six of them plus extended preludes. Daytime relationships and nighttime danger give it a social, modern shape. It is an excellent branch for a group that likes character interaction and does not need every scenario in one linear order.

Edge of the Earth is an Antarctic expedition with a large supporting cast and a strong sense of travel, isolation, and attrition. The Campaign Expansion is story; the Investigator Expansion is the broadly useful multi-class card library. The Forgotten Age leans into expedition logistics and consequences. The Innsmouth Conspiracy brings coastal pursuit, memory gaps, and bless/curse deck support when paired with its investigator cards. Both are better once the table accepts that a campaign may push back hard.

The Scarlet Keys uses an open world-map structure and more reading between scenarios; it is a taste-specific later purchase, not a default second box. The Drowned City is a late Chapter One descent toward R'lyeh and Cthulhu, atmospheric and relatively direct at the table, but more meaningful after the group has learned how Arkham evolves. The campaign stories are self-contained. You do not miss plot by choosing Carcosa before Dunwich or Hemlock before Edge.

Buy a standalone after the group has completed at least one full campaign or built investigators it wants to revisit. Murder at the Excelsior Hotel is the best first scenario-pack recommendation because its premise is immediate - the investigators wake in a hotel room with a body, police at the door, and an explanation to assemble - while variable leads and culprits give the case strong replay value. The real card spread shows hotel locations, guests, story acts, and multiple threats rather than player cards.

A standalone can be played alone or inserted into a campaign by paying the scenario's experience cost when instructed. The campaign guide remains the authority for timing and rewards. Do not buy Excelsior because it is cheaper than a campaign and expect it to replace eight sessions. Buy it for a convention night, a birthday table, a returning investigator deck, or the evening when the full campaign group cannot assemble.

After Excelsior, pick by event shape: The Blob That Ate Everything for pulpy spectacle and large-group energy, Machinations Through Time for synchronized teams, Fortune and Folly for a casino caper, The Midwinter Gala for social maneuvering, or Film Fatale for cinematic genre shifts. The Arkham Scenario Archive maps every pack without pretending one scenario is a campaign.

Skip old Deluxe Expansions and random Mythos Packs. They belong to the retired seven-product cycle model. Buy them only if you are deliberately completing an already-owned legacy cycle and have verified every missing pack. Wait on Return To boxes. They remix a campaign you already own with replacement encounter cards, alternate setup, and storage; they do not contain the original campaign. Their best audience has played the base arc enough to want changed assumptions.

Do not buy matching Campaign and Investigator boxes automatically. The matching art is a catalog convention, not a gameplay requirement. Buy a Campaign box when the table needs a story and an Investigator box when the card pool needs options. Do not pay a scarcity tax to preserve a recommended order. Fantasy Flight's 2026 Chapter Two shift has made some Chapter One stock uneven. Community threads repeatedly advise playing what you already have and refusing scalper prices.

Finally, avoid buying several full campaigns before finishing one. FOMO creates a shelf; completion creates expertise. The best time to buy the next campaign is during the last third of the current one, when the group can choose the next mood together and the purchase has a calendar attached.

Revised Core is enough to learn, replay the tutorial, and begin a full campaign. Add one Investigator Expansion when deckbuilding friction becomes visible: several players compete for the same staple, a class cannot express its role reliably, or the group wants more investigator identities. For the first broad library, Dunwich remains the easiest recommendation. For the strongest substitute or second library, Edge of the Earth touches many decks through multi-class cards.

Do not judge an investigator box only by its investigators. The lasting value is the number of useful cards that solve real deck jobs across classes: economy, draw, clue compression, enemy control, horror and damage management, movement, and test reliability. Conversely, do not buy a mechanically specialized box before anyone wants its mechanic. Innsmouth player cards become more valuable when the group wants bless and curse. Hemlock grows that ecosystem. Dream-Eaters spends card count on bonded and myriad designs that reward a larger library.

A good four-player table does not need a complete collection. It needs enough duplicate effects that everyone can perform a primary job without stripping another deck. Build roles aloud, proxy a shopping decision with cards you own, and add one box only when the missing function has a name.

The start-playing cart: Revised Core, sleeves for the two active investigator decks, and nothing else. Use the included bag, tokens, storage, campaign guide, and starter decks. A mat, coin capsules, wooden tokens, and premium dividers can wait until repeated play proves which friction matters.

The first-campaign cart: Revised Core plus the modern Dunwich Campaign Expansion. Add Dunwich Investigator only if the budget is comfortable or the player pool is already fighting over cards. The campaign and investigator boxes do not need to be purchased together, and neither expires because the other title is absent.

The story-shelf cart: everything at left, then the exact Carcosa Campaign product or verified two-box bundle, followed by Excelsior after the table has investigators it loves. This path creates a tutorial, two complete long stories, a broad player-card base, and one replayable event case. It is already a serious Arkham collection. The next dollar should go to the campaign mood the group chooses, not an imagined obligation to own every icon.

Before scenario one, give every investigator a deck box or labeled bag, record the deck list, and write a first-ten-XP plan. Separate the Core encounter sets from campaign-specific cards and keep the active scenario's sets together after play. Photograph the table before teardown if location adjacency is unusual. Update the campaign log immediately; unresolved campaign bookkeeping is how a three-week pause becomes a restart.

At the table, name roles: clue lead, enemy lead, and each player's emergency job. Read the act and agenda aloud before anyone spends an action. At the end of a round, ask whether the next action advances the act, prevents collapse, produces a real future tempo gain, or prepares a safe resignation. Arkham punishes beautiful turns that do not address the clock.

Between sessions, spend XP on the failure category the previous scenario exposed. If the group lacked clues, buy compression or reliable intellect. If one enemy consumed a whole round, improve damage or evasion. If decks never came online, lower the asset curve and improve economy. The Arkham Strategy Bible takes this from first campaign through hard-mode planning without turning the game into homework.

Play Revised Core twice. Buy Dunwich Campaign for the first full story. Buy Dunwich Investigator for the first broad card library. Buy Carcosa next for the strongest story escalation. Then choose Hemlock, Edge, Innsmouth, Forgotten Age, Drowned City, or another complete arc by table mood and normal availability. Add Excelsior when your group wants one special night.

That order is a recommendation, not a continuity lock. If Dunwich is scarce and Carcosa is available at a normal price, buy Carcosa. If the group wants island folk horror more than cursed theatre, buy Hemlock. If deckbuilding is the obsession, buy Edge Investigator before a second campaign. The stories do not require release-order plot knowledge, and campaign cards do not have to match investigator cards.

The only rigid rule is product identity. Campaign means story. Investigator means player cards. Old Deluxe means partial cycle. Return To means optional remix. Once those nouns are clear, the rest becomes the pleasant question Arkham was trying to ask all along: which nightmare does your table want next?
