Mars Matrix may be REALLY FREAKING HARD, but its still a lot of fun. The alternate mode and the shop options will just keep on drawing you back. But if you can ignore the insane difficulty, you wont regret purchasing a two-dimensional shooter for the Dreamcast.
An excellent effort that no shooter fan should overlook. The gameplay is solid even if it is a little on the difficult side, the graphics are decent, it has excellent replay value, and the overall presentation is top notch.
