About Calcium Contract
Calcium Contract drops you onto an island where a serpentine creature has defied the Calcium Order’s ancient law, “All that lives must die.” Summoned as an agent, you board a boat, wield a scythe, and begin a climb toward the creature’s lair.
The game blends the rapid‑fire feel of 1990s FPS titles with otherworldly weapons and a time‑rewind mechanic. Over twenty levels ascend the mountain, each demanding you read enemy behavior and adapt your deadly dance.
01 / THE GUIDE
Story Premise
The Calcium Order has enforced the law “All that lives must die” for millennia, but a serpentine creature seized an island and resisted their agents.
Your contract begins on a boat, scythe in hand, and leads you up the island’s mountain toward the creature’s lair, framing the campaign’s narrative drive.
- Watch early cutscenes for clues about the creature’s motives.
- Notice how the ancient law influences enemy design.

Core Gameplay
Combat draws inspiration from fast‑paced 1990s FPS games, yet your primary tool is a scythe and enemies each have distinct behaviors.
A rewind feature lets you jump back to any earlier point in a level or a few seconds before death, offering a safety net for mistakes.
- Experiment with the rewind to learn enemy patterns.
- Stay alert for enemies that manipulate others.

Level Structure
The main campaign spans over twenty levels that climb the island’s mountain, each introducing new enemy arrangements and environmental challenges.
Progression is linear; mastering cues in early stages prepares you for the increasing difficulty of later climbs toward the target’s lair.
- Treat each level as a step to master enemy cues.
- Observe how difficulty ramps with altitude.

Leaderboards compare scores with friends and other players, and daily challenges provide a single attempt each day to test your skill.
