Terra Nova - Strike Force Centauri

A brilliant computer real-time strategy/action game from Hothouse Creations which put you into a post-apocalyptic world plague by a deadly virus and an even more deadly alien threat, The Brood. You will take command of an elite squad of eight bio-mechanically enhanced super agents with other more earthly comrades to battle The Brood and their followers, The Faithful, to save the world from a dreadful future... It's like X-COM meets Syndicate Wars, with a wide arsenal of some realistic guns and other super-science-fiction weapons. Engaging gameplay!

You have been turned into a ball of air with a slow leak by an evil wizard. You must find the Spellbook and the ingredients for the spell. Without these, you will never turn back into a human again.

You're an airborne ranger working for the United States. You are dropped into different missions with different objectives. Some missions require you to retrieve a package in a given amount of time, and another requires you to rescue POWs. Carnage aplenty, as you can use different means to kill different foes. I had my first sadistic thrill in a PC game by using a LAW (light anti-tank weapon) to kill a single enemy soldier.
