Shoot First is, officially, a “co-op Action Roguelike” by the creator of Action Fist, Beau. If Desktop Dungeons is a cross between Nethack and Minesweeper, Shoot First is a cross between Nethack and the overhead-view stages of Super Contra.
The presentation is dusted with artifacts of retro glam grime. The simple three-button controls (shoot, strafe/use/pick up, and map) are snappy and responsive. Collisions and sound effects are crunchy and squelchy. On a superficial level it’s all very cozy and warm to sink into. Scattered in treasure chests are equipment and various weapons, each with its own uses. As you shoot enemies and collect stuff, your character levels up. As you level up, your weapons upgrade in various ways. Also along the way you can find or rescue followers, who trail after you and mimic your actions rather like Gradius Options.
