About
BastionOS is a chill active incremental game where you command a military terminal to stack ludicrous weapons and upgrades onto a lone tower facing an endless machine army. Destroy a gigantic evolving horde, get destroyed, unlock new tech, repeat, and get strong enough to survive the next level.
