Gem Rifts

Gem Rifts is a strategy game about leading an expedition through ancient portals to gather the gems needed to open more worlds. On each planet, you harvest resources and build defenses around the portal while hostile guardian life forms attack it. If the portal collapses, you will be stranded and unable to send gems back.

Protect the portal

Assign roles to workers and decide what to research as you prepare for attacks. Workers hunt, harvest, build and mine, then carry out their assigned tasks automatically. Attack waves target the portal, so you build Focal towers to defend it. Towers can burn, freeze, shock or disintegrate enemies, and combining towers creates new types.

Defeated guardians drop gems. You need gems to build towers and unlock new worlds, and must bring back as many as you can. Once you repel the final guardian attack wave, the portal is secure and you can return home.

Research and resources

A Research Tree unlocks more buildings, units and items. You can set worker roles with sliders and trade resources with other players.

Play alone or together

Play solo or in co-op with up to four players. The game includes unique defenders and towers.
