About Calcium Contract
"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.
- 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. A new challenge every day, but you only have one try!

Super 3D Noah's Ark got a sequel! You are Bob Boner, someone let out the crazy chickens and other animals out of the Ark. Your mission? Send them back to the shadow realm, so God can reset the universe (and make another Morbius movie). But for real, this is a fun, small, boomer shooter in a GZdoom style. The gameplay is simple but effective, I do enjoy the graphics and the level design. The music on the other hand is fantastic, some hits here for sure. Overall, I recommend this, get some calcium so your bones are strong, brothers & sisters :)2 found this helpful
This is honestly a hidden gem. Gameplay is smooth, weird and cool enemies, interesting and varied levels and the weapons, plus their animations, are really cool. Hope to see another similar game from this dev sometime soon.
WHATS A SKELETONS FAVORITE SNACK SPARE RIBS
This is really crazy. It's not gore and very colourful but it has the cruelty and the gunplay of a serious sam or a doom. Not to talk of the number of enemies that sometimes it's insane. Good job

TL;DR Exceptional short Boomer Shooter with a unique art style that breaks the trend of having a bad final boss! 8/10 Calcium Contract is a very cozy Boomer Shooter that I've refered to as "Doom for Babies". It's artstyle is very pleasant and as someone who read books like where the wild things are and other clay-model picture books and liked claymation movies like Coraline; This game is very nostalgic and is a constant fun time with only a couple downs. The main appraisal i can give CC is that it is exceptionally accessible. For my first playthrough i did it on Macabre the hardest difficulty and it took me no more then 3 total hours. Though i have some experience under my belt in the genre, this game is very welcoming as a first time experience for people breaking into the genre. it isn't that expensive at 10$, and although that may seem a little steep, i feel like it makes up for it with it's interesting additions. Though there's not a lot in the arsenal, everything is fun, feels really nice to use, and have a cute animation to them. The Trumpet/Starting weapon is very very good even on highest diff with 3 separate projectile that can also bounce around angles. So satisfying.…
