Zarlor Mercenary

The gameplay involves using a space ship to kill all enemy opposition on the way to the level end. Getting hit by their attacks lowers the health bar, leading to a life loss when completely gone. On the other hand, every killed enemy or destroyed building gives money that can be used between levels to buy upgrades like mega bombs (damages all enemies on the screen), a back cannon, extra lives, or a powerful shield.

Up to four players can participate in co-op gameplay, with the difficulty being only affected by starting out with less lives. Two additional upgrades are available for purchase: invisibility to hide from other players and a back stabber which damages other players instead of enemies.
