Three stores agree
No co-op
No. Steam files the game under Single-player. The PlayStation page says 1 player. The Xbox page says Single player. I do not see co-op, PvP, matchmaking, or split-screen in those three listings, and the patch notes I read do not add them at 1.0.
The Nexus Mods VOID/BREAKER listing showed seven files on 6 Nov 2026. That is a dated snapshot of that listing, not a complete mod census; none of the seven was identified there as a multiplayer mode. If you wanted a second person in the run, the public store listings describe a single-player game. Reviews comparing it with other roguelite shooters are on the review page.
In-game “mods” are weapon modules. They are not this Nexus folder. That split is the whole point of the mods page.
