Xeno Crisis

Xeno Crisis is an arena shooter where one or two players take control of battle-hardened marines who embark on a deadly mission to fight an alien threat and get home alive! Race and shoot your way through thousands of enemies as you explore the destroyed research outpost, search for survivors, and eventually face the source of the outpost's demise. Outpost 88 is divided into seven different areas that are randomly generated each turn, which means that you'll have to constantly adjust your strategy to successfully complete your mission. Collect dog tags from defeated enemies to improve your equipment between areas, and look out for special weapons that will give you a momentary advantage.
