==== Station ====
After arriving in a station bay, the marine reports to Master Sergeant Thomas Kelly for orders. He is tasked to find a missing scientist from the Delta Labs, which he indeed found later in a decommissioned communications facility, where he is frantically trying to send a warning to the UAC on Earth about Betruger's teleportation experiments. While the scientist attempts to explain the situation to the marine, a teleportation test gone wrong causing the hellspawn to arrive on the station at the same time turning severals personnels into zombies, marking the arrival of hell.
Forced to fend off attacks from zombified former personnel and demons from Hell, the Marine returns to the city of Mars, where Kelly gives him orders to link up with another squad of marines and get a transmission card containing a distress call to the main communications facility to call for reinforcements. Through out this entire progress, he learned that two other member Campbell and Swann have actually survived and are on their way to the communication facility to prevent any messages to be send in order to contain the situation on Mars.
On their way trying to stop the two, the Marine entire squad is wiped out by the demons in the EnPro Plant, despite he managed to retrive the transmission card, he is far long gone to prevent the bulk of equipment at the communications facility being destroyed by Campbell. However, Kelly gives the marine a guide to the backup system, where depending on his choices whether to obey Kelly's orders to send for reinforcements, or accept Swann's argument to keep Mars isolated in order to stop the demons from spreading into further more.
He is told to go for the Delta Labs either by Kelly or Swann, depending on wathever if the message is sent or not.
When he is on his way to the labotary, the marine is contacted by a traitor, Betruger. He wishes to use the reinforcement in order to transport the creatures to earth, if the marine did not send the reinforcement call, Betruger will be the one to do it. Betruger then unsuccessfully attempts to kill the Marine using the toxic gases in the base's recycling facilities. As he arrives in the lab, he learns about the true meaning and nature of the entire teleportation experiment, it was a foil made by Betruger to retrieve specimens with his increasing obsession with the tests, as well as of a xenoarchaeological dig under the surface of Mars. 
Inside the labotary, a scientist tells the marine that the invasion began when Betruger took the Soul Cube into the portal at the beginning of the game, depositing it in Hell. The Marine went after and pursuit Betruger through out the maps, but the teleportation pulled him inside of it as he falls to Betruger traps.
Arriving in hell, the marine fight his way through a large number of demons to the Soul Cube, defeating its demonic guardian. He then reinstalled the teleporter equipment left past resreachs experiments and returns to the Delta Labs. However, Betruger reveals that although the main teleporter entrance is destroyed, Hell has already opening a hellmouth that is capable of bringing a millions of demons to Mars. The Marine later find a injured Swann, who tells him that Kelly has possible been working with the demons for the entire time and could've transformated into something worse that they thought to be.
The Marine is given a PDA by Swann, who informs him that Campbell has went after him and the latter will try to escape the facility alone. However, when the Marine catches up with Campbell in the central computer processing sector of the base, Campbell is mortally wounded; before expiring, he says that Kelly has taken Campbell's BFG 9000 weapon. Being taunted by Kelly demonic voice, the Marine face off with him at the computer center core, revealing Kelly truest form as a cybernetic human grafted onto a tank-like base. With his personal experiences, the marine is able to kill off Kelly and take back the BFG 9000 as proceeding deeper under the Martian surface to Site 3, the archaeological dig site where the Soul Cube was unearthed.
Now at the primary extraction site, the Marine get to view the Hellmouth being guarded by hell mightiest warrior, the Cyberdemon. Using the Cube of Souls, the Marine defeats the demon and sealed the Hellmouth. Later on, he is seen being rescued by the reinforcements from earth who have came to discover the carnage. While Swann succumbed to his injures, the Marine is brought back to safety as it ends.
