In 1997 John Carmack released the Doom source code, allowing many developers to create their own variations on the original game, and above all, adapt it for use on modern operating systems. Several Doom ports now allow you to enjoy classic id Software titles (as well as others that use its engine) on modern desktop computers and Androids. But this doesn’t mean you can’t take advantage of the earlier titles and re-enjoy all of them just like the hormonal preadolescent you of yesteryear who filled his notebooks with pentagrams and pictures of Kurt Cobain. Not for nothing is the fourth installment of the saga coming out this Friday, 12 long years’ wait after the previous one. In 1993 id Software released what would become one of the most influential titles of the decade, both for its revolutionary approach and the controversy it would cause.
