“Everything that lives must die.” This ancient law has been successfully promulgated by the Order of Calcium for millennia. Until now. A strange serpentine creature refused, took over an island, and has been repelling the Order’s agents quite successfully.

You have been summoned and hired by the Order to solve the problem. You take your scythe and get on a boat.

  • A game that takes inspiration from the fast-paced FPS classics of the 90s, but from there goes in a slightly strange direction.
  • Fight your way through over 20 levels climbing the island’s mountain to reach your hired target’s lair.
  • You have at your disposal the unique weapons of the Order of Calcium. You’ll find them somewhat familiar but a little otherworldly in form and function.
  • Learn the behaviors of your enemies and use that knowledge in your deadly dance. Be careful, as some enemies can manipulate others to take you by surprise.
  • Mistakes happen. You can conveniently rewind time to any previous point in the level or simply go back a few seconds before your death.

Eternal Harvest is a unique score attack game mode in ever-changing procedural levels. It’s a brand new and super fun way to enjoy Calcium Contract!

  • Battle your way through procedurally generated levels that rebuild as you play!
  • Avoid or deliberately seek out Eternal Harvest curses. They increase your score but make the game more difficult in various wacky ways.
  • Compare your score with your friends and other players on the leaderboards.
  • Participate in daily challenges. A new challenge every day, but you only have one try!
