The player takes on the persona of an unnamed Marine (called, variously: Doomguy, or Marine, or even Doom Slayer) who is tasked with battling the inhabitants of Hell who have been unleashed upon a freshly colonised Mars by the evil antagonist, employee of Union Aerospace Corporation, one Olivia Pierce who has been promised wonderful things by Satan.įellow corporation employee, Samuel Hayden wants to stop her – but first he has to uncover her secrets, and for that he needs the Doom Slayer who swings into action, despatching demon after demon as he gets on the case. There would have been no double click to access the game: instead, commands would have to be typed into DOS to start play, that’s how long ago that was! Doom for PC is the fourth game in a series and a return to the origins, being a reboot of the highly acclaimed game that is something of the great-great grandpa of modern gaming – the first edition was released on MS-DOS in 1993, shortly after personal computing became widely normalised.
