What is Sanctum 2?
Sanctum 2 is a first-person shooter and tower defense game set on LOEK III, where aliens attack oxygen-producing Cores.

- +you want mission-based co-op with different character classes
- +you enjoy experimenting with weapons, towers, and perks
Not for you if...
- −you prefer passive tower defense without direct shooting
- −you want open exploration instead of mission-based defense
