Universal Warrior

Universal Warrior (or The Machines, as is the official title of the PC version) is a top-down maze shooter in the vein of Gauntlet and Alien Breed, with added economic elements.

The game alternates between equipment management and the actual in-level action, in which a remote-controlled robot runs through maze-like maps and shoots mechanical enemies. With the money earned in these sci-fi contests, improved equipment can be bought in five categories, making the robot more powerful, more maneuverable and less easy to damage. On the other hand, getting damaged means you must spend money on repairs. This encourages careful and effective playing.
