Zirconia 2: Battle is a unique 2D "space" shooter not set entirely in space. In this game, you and a computer-controlled opponent are playing vertical scrolling shooters, split-screen style. You must defeat 7 different opponents indirectly by using cards that you will draw throughout the course of the match. These cards will have various effects, such as spawning enemies on your opponent's side, or by sending projectiles over. There are also temporary stat-boosting effects and defensive structures you may set up.
