Ammossum Releases September 28!

Ammossum launches September 28!

After years of development, the train is finally ready to leave the station.

We've been working hard on the full version of the game, adding new weapons, items, railcars, characters, enemies, bosses, biomes, and much more.

The full release will bring everything we've been building toward, and we can't wait for you to finally play it.

See you aboard on September 28! 🚂
