About Calcium Contract

Calcium Contract is a fast-paced shooter inspired by ’90s FPS classics, with its own unusual direction. The Calcium Order has enforced the ancient law that “all that lives must die” for millennia, but a strange serpentine creature has seized an island and repelled the Order’s agents. You take a contract from the Order, take up your scythe and sail to the island to reach the creature’s lair.

Climb the island

Fight through over 20 levels as you climb the mountain toward your target. The Calcium Order’s weapons have familiar elements but otherworldly forms and functions. Learn how enemies behave and use that knowledge in combat; some enemies can manipulate others to catch you off guard. If you make a mistake, you can rewind to an earlier point in the level or jump back to a few seconds before your death.

Eternal Harvest

Eternal Harvest is a score-attack mode set in procedural levels that rebuild themselves as you play. You can avoid its curses or seek them out: they increase your score while making the game harder in various quirky ways. Compare scores with friends and other players on the leaderboards, or take on a daily challenge, which gives you one try.
