What is Sanctum?

In this sci-fi tower defense and first-person shooter, you build tower-lined mazes and shoot at waves of enemies. You defend across maps alone or with up to four players in co-op.

For you if...

  • +you enjoy planning enemy paths while fighting alongside towers
  • +you want cooperative defense against repeated enemy waves

Not for you if...

  • −you prefer an overhead view of your defenses
  • −you would rather build than shoot during battles

What players say

89% of 3,362 reviews are positive

Players praise the mix of tower defense and direct shooting, particularly in co-op. Some say the first-person view makes defenses hard to assess; others complain about clunky movement and repetitive tower choices.
