Doom - A pokol kapui
Doom - A pokol kapui (English: Doom - The Gates of Hell) is the first of two unlicensed Doom novels written by Hungarian author András Gáspár, working under the pseudonym of Damien Forrestal due to the unauthorized nature of the books. Both books were published in Hungary in 1995 by Valhalla Lodge. The second book, Doom - Tisztítótűz, is a direct sequel.
The giant Ukrainian powerhouse trooper Oleg Gontar, who possesses beneficial mutations inherited from his grandparents who survived the Chernobyl disaster, is paired up with the tactically brilliant but critically injured Captain A. A. Milne (named for the famous author) by having the man's consciousness uploaded into his own brain, creating a unique combination of brawn and brains. Together they are dispatched to a top-secret UAC research base on Mars where a disturbance has been reported. A maniacal priest Fuentes has broken out of imprisonment and obtained a mysterious alien object being researched at the base, known as the Mirror, which can make the thoughts of anyone nearby it into reality. Using the device, the priest has managed to unleash the forces of Hell.
