Background[]
Doom I Enhanced[]
You're a marine--one of Earth's best--recently assigned to the Union Aerospace Corporation (UAC) research facility on Mars. When an experiment malfunctions and creates a portal to Hell, the base is overrun by blood-thirsty demons. You must shoot your way out to survive. Doom II Enhanced Hell has invaded Earth, and to save it, you must battle mightier demons with even more powerful weapons.
TNT Evilution (Add-on)[]
Taking place after DOOM II: Hell On Earth, TNT: Evilution is set on the moons of Jupiter. With new leadership, and under strict government control, the UAC hoped the distance would keep them safe, but unfortunately a ship from Hell, disguised as an Earth supply ship, would catch the base off guard. As the lone survivor, you, the marine commander, must single-handedly tầke the base back for humanity.
The Plutonia Experiment (Add-on)[]
The UAC, trying to prevent any further invasions from Hell, begin work on new Quantum Accelerator technology in order to permanently close gates as soon as they appear. While initial experiments were successful, immediately cutting off Hell invasion forces, a coordinated invasion causes seven gates to open at once. The Quantum Accelerator is able to cut off six of them, but one still remains. With Hell in control of the Quantum Accelerator, and Earth's forces decimated, you must go deep into the base and regain control before it is too late.
