About Ammossum

This frantic roguelite shooter immerses you in a collapsing world where survival hinges on a relentless train journey through plague-infested territories. As the lone survivor, you navigate a hostile landscape filled with infected hordes, where movement is key and every stop could spell disaster. The game excels with its innovative ammunition-crafting system, allowing you to combine and upgrade projectiles into wild patterns of destruction, making every encounter feel unique and explosive.

Between battles, you manage railcars that provide resources and upgrades, enhancing your attacks and creating powerful synergies with your train. Each run follows a classic roguelite rhythm of combat, experimentation, and progression, but with a twist that ties your success to both your ammunition and your locomotive's capabilities. If you enjoy fast-paced roguelites with intricate weapon mechanics and a dark, chaotic atmosphere, this one's definitely worth a shot.

  4. Launch as Administrator: Right-click the main game executable and choose Run as administrator so local save files and configuration profiles write cleanly.
