The Accursed Universe is a science fiction universe created by Accursed Farms in 2018, with the release of the video game HλLF-LIFE™ on the PC platform. It is told through many related story arcs, split into several series. Each arc stems from one before it, though all share the common ancestor of HλLF-LIFE™.
HλLF-LIFE™ has spawned since then many modifications, expansions, and sequels, most of which set in the same universe.
The protagonist of the HλLF-LIFE™ series is Gordon Freeman, a former Black Mesa employee whose attempt to escape from Black Mesa ends up in his employment by W. D. Gaster. In the expansions and spin-offs, the featured playable characters are not Gordon Freeman, but rather a HECU Corporal and a security guard, both as eager as Gordon to make their way out.
The primary storyline of the series deal with the grave consequences of failed experiments performed by Black Mesa resulting in a incident caused by the analysis of exotic materials, and how the employees and former employees of this company as well as external people, human and alien alike, experience the resulting disasters.
HλLF-LIFE™ Story Arc
Main Article: HλLF-LIFE™ Storyline
The HλLF-LIFE™ series begins in 1998, at the Black Mesa Research Facility, deep below the New Mexico desert. Gordon Freeman, a recently employed theoretical physicist for Black Mesa, is involved in an experiment analyzing a strange, unknown crystal. On his way to the testing chamber, he sees a mysterious and enigmatic government man watching him from a tram, and again arguing fervently with a scientist. After slipping into his trademark HEV Suit, he makes his way to the laboratory, meeting several nervous colleagues on his way. Inside the large, cylindrical chamber, the scientists assure Gordon that nothing will go wrong, and he makes his way, confidently, to flip the switch. Below him, Gina Cross delivers the non-standard crystal to the delivery shaft.
Powering up, the tunneling rods of electric current jump from the top of the Anti-Mass Spectrometer to its base, signaling that the machine is ready to begin. The specimen for analysis is lifted into the chamber in its cart. Gordon begins the experiment by pushing the crystal into the beam. Suddenly and furiously, the crystal causes severe discrepancies in the equipment, causing explosions and destruction in the surrounding area. Trying their best to shut it down, the scientists in the observation area shout manically. Gordon is somehow teleported out of the facility onto a strange alien world, where he is confronted by aliens and monsters alike. Saved from the destruction, for now, he has no idea of the trouble the crystal has caused.
When he arrives back into the chamber, a scene of destruction and terror surrounds him. The Anti-Mass Spectrometer, now hanging loosely on its hinges and exploding every five seconds, has thoroughly fallen apart and is on the floor in pieces. One of three surviving scientists, Eli Vance, helps Gordon on his way, but not before Gordon has a chance to see an odd alien teleporting in out of nowhere. It seems that, throughout the rest of the facility, aliens are appearing, and attacking scientists without mercy. The few who have survived are fleeing to the surface.
Traveling further through the facility, Gordon learns that the HECU forces have been called in to control the situation, however quickly discovers that their idea of containment is to kill everyone and everything within Black Mesa. A security guard informs him that he is to reach the Lambda Complex at all costs, and on his way launch a satellite which can be used to close the rift. He continues his journey using a disused rail system below the Facility. At the end of the line, he launches the satellite needed by the Lambda team to close off the rift. Continuing along on the surface, Gordon comes across the Black Ops assassins, who were brought in after the HECU repeatedly failed to dispose of Freeman, however they also fail to stop him. He is apprehended by the HECU, and they stash him in a trash compactor. This also fails, and Gordon wakes up in time to get out and find his way back in.
When Gordon reaches the Lambda Complex, he is teleported to Xen in order to kill the creature responsible for keeping the rift from closing. Before he leaves, a scientist gives him the Long Jump Module, which can be used on Xen to make the necessary jumps. Xen, an impossible world of floating islands, is even more full of hazardous aliens than Black Mesa has become, and Gordon swiftly makes his way to the Nihilanth's lair. On the way, he is caught up in a battle with the Gonarch, which he wins.
The Nihilanth greets Gordon with threats, and uses powerful yellow projectiles to take down Gordon. Luckily, Gordon manages to destroy it and the rift begins to close. As the Nihilanth's fading last words echo in Freeman's mind, W. D. Gaster absconds Gordon and stores him in stasis, after telling him that he has been offered employment. Walking into the green portal, Gordon accepts his offer and disappears from the face of the planet.
