What co-op raids are
Co-op raids are 8 Bit Tower Defense's dedicated multiplayer raids mode. The official game description lists them under the player icon line: "Co-op raids for up to 4 players: Rift Gate, Coral Cove and Eclipse Spire" — so a raid is a run you take on together with other players rather than solo, with a cap of four participants and a choice of three locations.
Raids are also a distinct entry in the game's mode lineup, not a variant of something else. The same official listing separates raids from Expedition (one squad, three worlds, and you pick a Relic after every win), Infinite mode, rotating challenges and the World Boss. If you want a comparison of everything on offer, see the full 8 Bit Tower Defense game modes overview.
The three raid locations
You can choose between three named raid locations:
- Rift Gate
- Coral Cove
- Eclipse Spire
All three come straight from the official game description, which names them as the co-op raid destinations. The available material names the locations but does not describe how they differ from each other in layout, enemies or difficulty, so treat them as the three maps you can pick a raid in.
How many players can join a raid
A raid supports up to 4 players. That is the stated maximum, so a raid group can be anywhere from you alone up to a full four-player squad. For the broader game basics — placing units, upgrading, and clearing waves as a team — the how to play guide covers the core loop.
Where to find Raids in the game
In the game's Play menu, RAIDS appears as one of the selectable modes alongside STORY, EXPEDITION, CHALLENGES and WORLD BOSS. At the time it was observed in gameplay footage, the RAIDS entry displayed the text "Clear Ashen Citadel". That wording suggests a connection to the Ashen Citadel — the final story world — but its exact meaning (whether it is a progress marker or an unlock requirement for raids) is not established, so don't take it as a confirmed condition. The Ashen Citadel guide covers that world in detail if you are working through story progression.
Teaming up before a raid
8 Bit Tower Defense has a party system you can use to group up: you can form a party and invite other players to join it. In one observed session, a player invited people with a "Join my party" call-out, another player joined, and the two then played a wave together. That observation comes from general gameplay rather than a raid specifically, so it shows the game supports inviting others into your party and playing co-op with them — a general co-op feature, though the available material does not show how raid teams are formed. For other co-op and solo activities outside raids, the Expedition guide breaks down the squad-based Expedition mode.
Quick recap
Co-op raids are the multiplayer raid mode of 8 Bit Tower Defense: up to 4 players per raid, three raid locations to pick from (Rift Gate, Coral Cove and Eclipse Spire), and the RAIDS entry sits in the Play menu next to Story, Expedition, Challenges and World Boss. The party system lets you invite other players to play together; the available material does not establish how raid teams are formed.
