Doom II: Hell on Earth is a first-person shooter developed by id Software and released in 1994 as a sequel to the original Doom. The game continues the story, with players battling through Earth after it has been invaded by demonic forces. Gameplay remains similar to its predecessor, featuring fast-paced combat, maze-like levels, and an array of weapons, including the introduction of the powerful Super Shotgun. Doom II also adds new enemy types, such as the Arch-vile and the Mancubus, increasing the game's challenge. Initially released for MS-DOS, Doom II has since been ported to numerous platforms, becoming a cornerstone of the FPS genre.

In the future, humans have left Earth and settled throughout the galaxy. On Mars, the Union Aerospace Corporation has established a radioactive waste facility and allowed the military to conduct teleportation experiments on the nearby moons of Deimos and Phobos. Hours ago, the base on Mars began receiving incoherent distress messages from Phobos, while Deimos has disappeared completely. With all attempts to establish contact failing, you and your team have been dispatched to investigate. Upon arrival, you secure the perimeter as the rest of your team enters the facility. As you stand guard, your radio crackles with the sound of gunfire, cracking bones and blood-curdling screams and eventually falls silent. Alone, with no way off the planet or means to defend yourself other than your trusty pistol, there’s only one way out - into the complex of death and the horrors that await you within. If you plan to get out of here alive you must fend off the hordes of demonic imps, haunting spectres and your undead, former comrades waiting to tear you limb from limb. So, grab the nearest shotgun and blast your way out of this fragging madness!

Set on a distant planet named Bazoik, the game follows the Chex Warrior, a humanoid in an anthropomorphic piece of Chex cereal armor, as he fights to eradicate the Flemoid invasion. These slimy, green creatures have infested the planet and captured many helpless citizens whom the Chex Warrior must save. His only weapon is a device called a "zorcher", which teleports his enemies instead of killing them. The game starts at the landing pad of the research facility on Bazoik, after which the protagonist is teleported to the storage facility. The other levels include the laboratory, the arboretum, and finally, the underground caverns of Bazoik, where the Flemoids seem to be making a home for themselves.

Three brothers, known as the Serpent Riders, have used their powerful magic to possess seven kings of Parthoris into mindless puppets and corrupt their armies. The Sidhe elves resist the Serpent Riders' magic. The Serpent Riders thus declared the Sidhe as heretics and waged war against them. The Sidhe are forced to take a drastic measure to sever the natural power of the kings destroying them and their armies, but at the cost of weakening the elves' power, giving the Serpent riders an advantage to slay the elders. While the Sidhe retreat, one elf, sets off on a quest of vengeance against the weakest of the three Serpent Riders, D'Sparil. He travels through the "City of the Damned", the ruined capital of the Sidhe, then past Hell's Maw and finally the Dome of D'Sparil.

In a twisted medieval dimension, undead creatures and bestial horrors have done the unthinkable--callously slaughtering your entire race. Your friends. Your family. Eliminated. But the nightmare has just begun. Wielding ungodly weapons such as the Firemace and Hellstaff and casting spells from the Tomes of Power, you must seek your vengeance. Or die trying.

While you were battling the evil forces of D'Sparil, the other Serpent Riders were busy sowing the seeds of destruction in other dimensions. One such dimension is the decaying world where Hexen takes place. A world littered with the mangled corpses of nonbelievers and inhabited by the undead followers that executed them. Only three humans; a warrior, a mage and a cleric; have escaped the leaders' vicious spell. Now these brave souls have sworn to crush the evil regime that threatens to destroy the world forever. Separated upon entering the mystical portal, the three are forced to attempt on their own what they had hoped to do together: find Korax's stronghold, destroy him and restore order in the physical world. Become one of 3 heroes. Wield superhuman powers and lethal weapons. Walk. Run. Fly. Look all around. Inflict serious pain. Pillage your way through earthquakes, crumbling bridges and fog. Track down powerful artifacts and cast wicked spells. Four sick individuals can wreak havoc via network, two by modem.
