Gridlock is an arena-based shooter that sees you take control of four gun turrets. In the middle of the grid, a variety of abstract yet lethal geometric shapes emerge which will destroy your turrets. Unless, of course, you can shoot the shapes first. Game over comes when/if all your turrets are destroyed.

Gridlock harkens back to a time when games were about beating your own high-score and also about shooting abstract shapes. Nothing more, nothing less.
