Doom 2 Guides and Walkthroughs
Doom II for the Game Boy Advance was developed by Torus Games of Australia and published by Activision. It was released on October 23, 2002. This version of the game does not run on a port of the original Doom engine. Instead, it runs on a custom machine shared with several other Game Boy Advance first-person shooter games called the Southpaw Engine.
The game is nearly identical to the PC version in terms of content, with only very minor changes. However, conversion of the gameplay and rendering functions to a different engine resulted in several visual and mechanical inconsistencies from the original game; some are purely cosmetic, but others can have a significant—and sometimes detrimental—effect on gameplay.
