The game starts with the player arriving at the on-site M.A.G.M.A facility at some point in year 2030. After meeting with the local commander, General Baker, the player goes on their first mission: searching for survivors within the facility while fending off waves of aliens. Non-player characters in this mission include Nicholas, an engineer who provides rewards if the player fulfills his requests, and Kate Lia, a mercenary hired by M.A.G.M.A. who is abducted by the aliens when the player becomes trapped in the facility's computer room. While at the facility the player is also asked to disable a self-destruct program that threatens the facility. Once the program has been shut down, General Baker concludes that the aliens must have a leader, and it is the leader who activated the self-destruct program. The player also discovers that the M.A.G.M.A. Energy Corporation has made a deal with General Baker in sometime, asking him and the rest of the mercenaries to shut the entire base down in return for a large amount of money. The player is then sent to the next facility, the ME2 Base. After battling through hordes of aliens, the player finally manages to enter the ME2 Base. While clearing more aliens from inside the base, the player is asked to download research data and destroy some experiment capsules. General Baker asks the player to rescue Kate after M.A.G.M.A.'s research is destroyed. He has located an alien breeding ground deep within a coalmine nearby and sends the player and a few soldiers to destroy the breeding ground, eliminate the Alien Queens (Alien Mother Scarabs), and remaining aliens once and for all. Before reaching the final room, the alien's leader and Baker will both tell the player to give them the research disk and the alien leader threatens that Kate will die if the player doesn't give him the disk. After that, the player will need to make a choice. If the player chooses to go to the alien leader and save Kate, General Baker will scold the player for disobeying him. He also reveals that the downloaded data contains information on how to control the aliens and that he plans to use it. In a confrontation with the player, Baker true goal to rule over mankind was revealed and had to be killed. On their way to save Kate, the player engages the aliens, leading to a final battle in which the player kills the Alien Basilisk (alien leader). After defeating the alien leader, the player discovers that Kate is dead already by the time the player reaches her. The disk containing the data on controlling the aliens and the portals is destroyed. Without the leader control, factions in the alien army have begun to fighting each other instead of attacking humans, enabling human military to take down the disorganized alien force gradually over time. The game ends as cities suffering from alien invasions begin to recover peacefully. However, if the player decides to go back to General Baker instead of rescuing Kate, the alien leader will send teleporting minions to attack him and gives the player as one final warning. If the player gives Baker the disk, he will teleport away, and M.A.G.M.A. will order the player to find General Baker as quickly as possible. After the player finds the remains of Baker strewn throughout a M.A.G.M.A. base, the Alien Basilisk organizes the alien hordes into a powerful organized army and manages to overrun most of the major cities, causing most of the humans to perish, the Earth Government using nuclear weapons to destroy cities overrun with aliens, and M.A.G.M.A. still trying to recover its experimental energy weapons, all these events being described in the final journal entry of the last human on earth.
