New Warhammer 40,000 Event Companions Lock In One Force Disposition

Games Workshop has split its Warhammer 40,000 tournament rulebook into four Event Companion documents, a week before the 11th edition lands in stores. The new the new Warhammer 40,000 Event Companions download, posted to Warhammer Community on Friday, covers Main, Doubles, Teams, and Dominatus formats, and it locks every player into a single Force Disposition for the whole event.

The release lands about a week before the new boxed set Warhammer 40,000: Armageddon hits shelves, the launch vehicle for the 11th edition first shown at the the 11th edition reveal covered in the Sunday Preview. The Main Event Companion carries the full list of unit base sizes for the new edition, the recommended terrain layouts, and revised mission sequences. The other three files sit alongside it as supplements for non-standard formats, with the old single Tournament Companion from 10th edition gone entirely.

Four Documents Take Over From the Old Tournament Companion

The Main Event Companion runs players and tournament organisers through the standard one-on-one format, and it sits at the centre of the new structure. Alongside it, Games Workshop has shipped three supplements covering Doubles, Teams, and Dominatus play, the first time Doubles and Teams have had their own dedicated tournament documents.

The 10th edition Tournament Companion carried all of that material in a single PDF, and the split is more than cosmetic: each supplement now sets out the rules corner cases that format actually triggers, instead of leaving players to hunt through a master document. The Main companion handles standard events, base sizes, terrain layouts, and the new mission sequence. The Doubles file covers two-player team games, including the new Unified Force and Force of Convenience distinction. The Teams document lays out pairings for three-to-eight player teams, and the Dominatus file supports narrative campaigns built around the deck included in the Armageddon boxed set.

The four files are available to download from the Warhammer Community Downloads page, with French, German, Spanish, Italian, Japanese, Korean, and Chinese translations published alongside the English originals. Mission layouts will move into the updated Warhammer 40,000 app from next week, where most players and tournament organisers will end up looking them up at the table. Tournament organisers running their first event in the new edition will be working from a fresh document set, with no carry-over of the old 10th edition files.

The Force Disposition Lock and Its Three-Layout Terrain Twist

The single rule that defines the new Event Companions is the Force Disposition lock. Players pick one Force Disposition based on their army’s detachments when they submit their list, and that choice is set for the entire event, which means each player faces the same five primary missions across all their games.

Those single Force Disposition choices are paired with a second mechanic that tournament organisers will care about most. The Event Companion ships a set of three terrain layouts (A, B, and C) for each Primary Mission, with guidelines on which rounds should use which letter. Players now set up the terrain on their table after being paired, rather than playing on a standard layout in every game, and the layout a player gets can change the feel of the same Primary Mission into something close to a different mission. The Terrain Area Footprints download is already available from the Warhammer Community Downloads page, and the full Tabletop Battles review of the 11th edition Event Companion gives diagrams and measurements so the table can be ready fast.

The mission sequence is a 14-step run from list submission to final score, with the Force Disposition pick landing at step 1 and the table set-up pushed to step 4 so the layout is matched to the pairing. A second piece on the 14-step mission sequence breakdown walks through each step in order, with two paragraphs on how the Secondary Mission secret selection at step 6 and the redeploy rules at step 9 interact with the new sequence.

Scoring caps sit on the Primary and Secondary Mission totals, with a separate 20VP per-card cap on Fixed Secondaries. A Battle Ready army adds 10VP at the end of the game, on top of the 45VP caps on Primary and Secondaries. Primary Mission VP is capped at 15VP per battle round, with the same 15VP-per-round ceiling on Secondaries.

Doubles Gets Its Own Ruleset, and the 3DP Question Is Settled

The Doubles Event Companion is the first dedicated tournament file Games Workshop has published for the format, and it spends its early pages sorting out the rules interactions that only show up when two players share a board. Each player brings a 1,000-point army and the two form a single force, with a Unified Force (matching faction keywords) treating aura abilities, Transports, and army rules as one pool, and a Force of Convenience (mixed factions) keeping most rules army-by-army. Command points are shared at the force level either way, with one extra CP per round and one Warlord per team. The file answers the most common Doubles corner cases in plain language.

Do you gain extra command points because there are two of you (nope), or can your Ork Boys hitch a ride in your mate’s Wave Serpent (also nope).

The 3DP detachment question is settled in the same file. The Warhammer Community article on the Tournament Companion confirms a 3DP detachment can be used as a single detachment at 1,000 points, even if that detachment normally costs more Detachment Points than the mission size technically allows, and the change is going into the first post-launch update to the Muster Army rules. The clarification matters beyond Doubles, because the same rule will apply in standard 1,000-point games where an Imperial Agents or other low-detachment army wants to bring its main detachment without burning the whole DP budget.

Teams Events Now Run on Blind Defender Picks

The Teams Event Companion is built for team sizes of three to eight players per side, with cumulative scores deciding each round. The format keeps the Force Disposition lock from the Main companion, then layers a per-team selection cap on top.

For every five players on a team (rounded up), only one player can pick each Force Disposition. A five-player team must field all five Dispositions exactly once, and an eight-player team carries every Disposition once with three players doubling up. The cap forces a team to master different mission types instead of stacking the strongest Disposition across the board.

Pairings run on a blind Defender and Attacker pick. Each team secretly selects a Defender and two possible Attackers, both Defenders reveal, both teams then secretly select which Attacker they want their Defender to face, and each Defender gets to choose which mission layout to play. The mechanic is meant to force teams to read the board, rather than just submit the strongest list they have. The Event Companion notes that the system is tweaked slightly depending on team size, and the full Teams file carries the per-team-size modules in detail.

For a three-player team, the round runs through a Main Engagement module; a five-player team adds Initial Skirmish; and an eight-player team runs Initial Skirmish twice, Main Engagement, and Champion System.

Dominatus, the Updated App, and Seven Translations

The Dominatus Event Companion is the smallest of the four files, and it sits closest to the narrative end of the new edition. The companion is built to run Dominatus campaigns at organised events, using the deck included in the Warhammer 40,000: Armageddon boxed set, and it gives tournament organisers advice on adapting the deck and tips on how to pair off players across the weekend. Games Workshop has confirmed the deck will be available to pre-order separately from the day after the Event Companions dropped.

The mission layouts will move into the updated Warhammer 40,000 app from next week, with more details promised shortly. The app has been the main way many tournament organisers and players have looked up matchups in past editions. The move keeps the layout PDFs and the in-app mission rules in step at launch, so the table a player walks up to is the same table the app describes.

The four Event Companion documents are also available in seven non-English languages:

• French
• German
• Spanish
• Italian
• Japanese
• Korean
• Chinese

Translating tournament documents at launch is unusual for Games Workshop, and it lowers the bar for organised play in markets where the English files have historically been the only option. The full set is listed alongside the English originals on the same Warhammer Community download page.

Tacoma, Newport, and Kraków Open the New Tournament Calendar

The first three Warhammer Opens of the new edition are already on the calendar, and each will be the first event in its city to use the new documents. Tacoma in July is the perennial flagship and is expected to draw more than 500 players. Newport, Wales, follows in August as the first Warhammer Open ever held in the city. Kraków closes the summer run in September as the inaugural Warhammer Open in Poland, and Kraków is built specifically around Team Warhammer, the format that gets its first dedicated tournament document this edition. The Kraków dates are the first to be confirmed in the Kraków, Atlanta, and Palm Springs Warhammer Open dates announcement.

• More than 500 players expected at the Warhammer Open in Tacoma, in July.
• First Warhammer Open in Newport, Wales, in August.
• Inaugural Warhammer Open in Kraków, in September.
• First Open built around Team Warhammer, at EXPO Kraków in Poland.
• 2026 calendar runs to nine Warhammer Opens in total, per the announcement.

Tickets for Kraków, Atlanta, and Palm Springs went on sale at 7pm UK time on 12 June, and the 2026 Open calendar now runs to nine events in total. Tacoma tickets were already on sale at the time the Event Companions dropped, and the flagship field in July will be the largest single test of the new rules. With one week to launch and the Event Companions already in players’ hands, the first tournament round of the 11th edition is the moment every format change goes live.

Frequently Asked Questions

What is a Force Disposition in the new Warhammer 40,000?

A Force Disposition is the new army-building option in 11th edition Warhammer 40,000 that ties a player’s mission pool to the detachments in their list. At an event, a player picks one Force Disposition when they submit their army list, and that choice is locked for the whole event, so they only need to master the five primary missions linked to that Disposition.

Where can I download the new Warhammer 40,000 Event Companions?

All four Event Companion documents (Main, Doubles, Teams, and Dominatus) live on the Warhammer Community Downloads page, with French, German, Spanish, Italian, Japanese, Korean, and Chinese translations published alongside the English files. The mission layouts also move into the updated Warhammer 40,000 app from the week of the 11th edition launch, so the same maps a player studies on paper are the ones in their phone at the table.

Can a 1000-point Doubles army use a 3DP detachment?

Yes. The Doubles Event Companion sets out that a 3DP detachment can stand alone in a 1,000-point Doubles army, and Games Workshop has flagged the same allowance for the first post-launch update to the Muster Army rules. The clarification carries into any 1,000-point format, not just Doubles, so an Imperial Agents or other low-detachment army can bring its main detachment without burning the full DP budget.

When does the 11th edition of Warhammer 40,000 launch?

The 11th edition launches about a week after the Event Companions dropped, with the Warhammer 40,000: Armageddon boxed set as the launch product. The Event Companions landed on June 12, 2026.
