Before you start the next level, you get a little story: (3)

The planetary policy was clear. You could not go near Mars or it's moons. This was guaranteed by the extreme levels of radiation surrounding the bases. The Dark corridors and large rooms that held the carcasses of demons sat motionless, abandoned. The bases locked and sealed. However, there was some movement. A single Entity that could resurrect the dead, was still living. Though extremely wounded, the monster was able to bring back the dead demons. Masked by the extreme radiation, it was able to resurrect the monsters until a decayed satellite noticed something. The near busted probe sent it's last transmission to earth. The U.A.C was horrified. Fearing an outbreak, they sent the bad-ass lone survivor of The DOOM episodes: you. Your mission is clear. Kill all the demons or they will kill you.
