Calcium Chaos: Derailed

About

Calcium Chaos: Derailed is a chaotic twin-stick shooter where you command a train to battle undead hordes. You and a crewmate (or AI ally) steer a customizable locomotive through levels, firing wacky weapons at skeletons while dodging obstacles. Upgrades boost speed, armor, and firepower, but you’ll need to balance resources between defense and offense. Co-op play adds frantic teamwork, protect your partner as you blast through tunnels and forests, all while a goofy narrator comments on the carnage. The game’s absurd humor and escalating action set it apart. With 20+ upgrade paths and randomized encounters, no two runs feel the same. Players praise its tight controls and escalating difficulty curve, which keeps matches tense even after multiple runs. While the story is a thin excuse for the mayhem, the over-the-top weapons and lovable train mechanics make it a standout pick for fans of fast-paced co-op shooters. Available on PC and Mac, it launched November 2024 to a 85% positive reception on Steam.
