About BastionOS
BastionOS is a short active incremental game about defending one tower against a machine army. You pick a level, aim the tower's artillery at incoming enemies and grab the resources they drop.
The tower will fall. Each time it does, you fortify it with more weapons and upgrades and research new tech, so it rises stronger. Over time the defences get ludicrous, and so does the horde, which keeps evolving to match you. You and your weapons programme are humanity's last line of defence.
Feral Paw released it on Steam on 28 April 2026 for Windows and Mac, at £2.81. Its 178 reviews are Very Positive.
