"All that lives must die". This ancient law has been successfully enacted by the Calcium Order for millennia. Until now. A strange serpentine creature refused, took hold of an island, and has been repelling the Order's agents rather successfully. You have been summoned and contracted by the Order to solve the problem. You take your scythe and get on a boat. Features A game that takes inspiration from fast-paced FPS classics from the '90s, but moves from there in its own slightly weird direction. Fight through over 20 levels climbing the island's mountain to get to the lair of your contract target. You have the unique weapons of the Calcium Order at your disposal. You'll find them somewhat familiar yet a bit otherworldly in form and function. Learn your enemies' behaviors and use that knowledge in your deadly dance. Be warned, as some enemies can manipulate others to throw you off guard. Mistakes happen. You can conveniently rewind time to any earlier point of the level or just jump back to a few seconds before your death. Eternal Harvest Eternal Harvest is a unique score-attack game mode in ever-changing procedural levels. It's a completely new and super fun way of enjoying Calcium Contract! Fight your way through procedurally generated levels that rebuild themselves as you play! Avoid or deliberately seek out Eternal Harvest curses. They increase your score but make the game harder in various quirky ways. Compare your score to your friends and other players in the leaderboards. Participate in daily challenges.
