Calcium Contract

Calcium Contract launched on October 17, 2023 as a complete fast-paced FPS with over 20 campaign levels. The developer shipped one meaningful post-launch content addition: the Eternal Harvest mode on June 5, 2024, a free update adding a full procedural score-attack game mode with daily challenges and leaderboards. Following that release, the developer shipped several small patches addressing bugs, gamepad support, and balance tweaks, with the most recent update on March 14, 2025. With only one major content drop in the game's lifetime and no developer statements about future updates, expansions, or roadmaps, there is no established cadence of ongoing major content releases to suggest more is coming. The sole DLC listed is the game's soundtrack, which has been released. The store description presents the game as a complete package — the base campaign plus the Eternal Harvest mode — with no mention of planned future content. The developer has made no announcements of upcoming additions since the Eternal Harvest launch. The game appears to have shipped as a finished product and received one substantial free expansion, with only maintenance patches since then.
