Alien Shooter: Vengeance is a top-down shooter for Microsoft Windows developed and published by Sigma Team in 2007 as a sequel to Alien Shooter. An improved version called Alien Shooter 2: The reloaded features have changed the game mechanics and a few new levels.
In 2030, M.A.G.M.A. Energy Corporation sends its mercenaries to a top secret target. Terrible and dangerous experiments were held there and now they are out of control. The player must complete a series of missions, destroying anything and anyone in his path.
The game begins with the player arriving at the on-site M.A.G.M.A facility. After meeting with the local commander, General Baker, the player goes on his first task: finding the survivors in the facility while fighting off the waves of aliens.
Non-player characters in this mission include Nicholas Engineer, an M.A.G.M.A. Staff provide rewards if the player meets his requirements and Kate Lia, a mercenary hired by M.A.G.M.A.
It’s the one kidnapped by aliens when the player is trapped in the facility’s computer room. While at the facility, players are also required to disable a self-destructive facility threat program. Once the program was closed, General Baker concluded that the aliens must have a leader, and it was the leader who triggered the self-destruction program.
Players also discovered that M.A.G.M.A. The Energy Corporation made an agreement with General Baker, asking him and the remaining mercenaries to close the entire base to return a large sum of money. The player is then sent to the next base, Base ME2.
After fighting the aliens, the player finally gets to the ME2 base. While clearing there are still many aliens from the base, players can download data showing that M.A.G.M.A. studied ways to control the alien army, but an accident caused them to be aggressive in the entire facility.
General Baker asked the player to rescue Kate after the research of M.A.G.M.A. destroyed. He placed an alien breeding ground deep inside a nearby coal mine and sent it to the player and a few soldiers to eliminate the aliens once and for all.
