Heaven's Machine is a chaotic, fast-paced roguelite set on a cosmic train racing towards heaven. Jack wakes up to find themselves at the end of this metal tomb, with no other choice than to pick up a gun, pull the trigger, and run headlong towards the conductor to save their dead loved one.

As Jack, players will travel through a randomly-generated train, grabbing dozens of the 50+ unique items, blasting hundreds of enemies, and battling bizarre monsters. For an extra challenge, battle the demiurge in the unlockable Night Train mode which randomizes all train cars, enemies, bosses, and shops!
