What is Kritter: Defend Together?

You defend the spaceship M. Ark in a top-down action roguelite that combines fighting with tower defense, solo or online with up to four players. Across three procedurally generated levels, you gather resources between enemy waves, construct walls, traps, and turrets, then return to repel attacks. Most upgrades disappear when a run ends, but Soul Crystals unlock permanent improvements.

For you if...

+you enjoy balancing exploration time against an approaching attack
+you want an endless mode for longer defense sessions

Not for you if...

−you want uninterrupted fighting without resource gathering or construction
−you expect all upgrades to carry over between runs
