Under A Rock is an open-world survival craft game, players must build, craft, and explore to survive and succeed on a colorful but mysterious and perilous island.

Under A Rock puts players smack dab in the middle of a colorful but mysterious new land. Stranded and faced with flora and fauna that diverted along various new evolutionary paths, along with mystical curses and illnesses, players will need to set up camp, gather resources, and explore this strange island setting full of mysteries and wonders. With multiplayer co-op for up to 10 players, friends can take on this survival challenge together.

Walk the path of an early nineteenth-century explorer, recently stranded in an exotic and strange new land. A world draped in mysteries once thought lost to time, this land experienced completely different evolutionary paths, with exotic creatures roaming dangerously. 

Survivors can build a base, explore dark caves, swim through underwater environments, and traverse a diverse surface world, facing a myriad of unique challenges and discovering much-needed resources. Players must fish, fight, farm, craft, and more as they build their new island base and hope to fight off the forces of nature and terrifying curses.

Under A Rock utilizes procedural level generation to offer a new gameplay experience every playthrough. With multiplayer co-op available for more than 10 people and a deeply diverse character creator, players can look forward to surviving a vast new world of fearsome flora and fauna together. 

In this untamed world, survival means facing down prehistoric threats with nothing but primitive weapons and quick reflexes. The latest gameplay footage reveals intense encounters with Neanderthals, a brutish new enemy group that vigorously protects their territory. Players must master skill-based dodging and well timed shield blocks to survive their attacks, retaliating with an arsenal of handcrafted clubs, spears, axes and bows.

Combat in Under a Rock is primal and dynamic, demanding good timing and tactical thinking. The fluid enemy animations and unique attack patterns that ensure each encounter feels distinct and dangerous. Every swing, dodge, and block feels weighty and impactful, creating a combat system where reflexes and weapon mastery determine who survives.

Set in a procedurally generated open world shaped by an alternate evolutionary timeline, Under a Rock blends action, exploration, base building, creature taming, and survival into a colorful, unpredictable sandbox. Whether exploring solo or teaming up in groups of up to 10 players, adventurers must navigate a world that’s as whimsical as it is wild.
