Game Description:Second add-on to Alien Shooter (also known as Invasion: Earth in the UK). This expansion is set in 2026 AD. One year passed since aliens invaded planet Earth. The monsters have captured large districts of the Earth surface, and now all the humanity rises against them. Among secret government research projects there's a virus which can help people survive and avoid total annihilation. You must get into the secret research-and-development center and save the virus. Features include five new missions, put together in a plot line, additional prehistory and even larger crowds of monsters to wipe out before you reach the goal.
