About this game

Cogwork Bastion is a steampunk tower defense where you place Piston, Tesla, Foundry, and Vent turrets on a grid to shield a central foundry core from waves of clockwork enemies. Switch your bastion's polarity between Steam and Voltaic to match each enemy and deal double damage, and trigger chain-reaction cascades when packed foes explode together. Build adjacent towers of the same type to sync them for faster fire and more cogs.
