Sanctum builds its defense around a mash-up of planning and direct combat. Rather than watching a tower-defense setup from the sidelines, players can join the fray in a first-person shooter format, making the shift from preparation to fighting part of the game’s identity.
Maze construction gives the defensive planning a distinct twist: the game encourages players to shape routes, not merely place towers. A customization system adds further room to tailor a setup. These building choices sit alongside action gameplay, while hidden secrets and Easter eggs offer discoveries beyond the core defense loop.
The store description lists single-player and multiplayer, with co-op support for up to four players. That mix gives player-count figures useful context: Sanctum is designed for both solo play and cooperative sessions, rather than being exclusively a multiplayer experience. Its combination of maze-building strategy and first-person combat is the defining frame for understanding activity around the game.
