The gameplay is quite different, of course, with AvP being a more tactical, slower paced, maze-like game that was a survival-horror game before that genre even existed. Both the original Doom and AvP are FPS games, both from the same era of gaming, both with similar resolution and functions. This is no easy feat, but not the most difficult either. GZDoom is an advanced source-port of the Doom engine, allowing OpenGL graphics, scripting, new features, etc. I am recreating the gameplay and features of the Jaguar game, AvP, in GZdoom. A crappy save system due to very limited space on the cartridge (OMG, remember those?) which had somewhere around 256 byte…bytes, folks, not kilobytes or megabytes…of storage space, meaning all they could save was your player class, location, and weapons/ammo/keys, and all enemies and items would respawn upon loading. A shoddy frame-rate due to Atari’s limits on what developers could use the processors for (some devs ignored the rules, and their games run at a slippy-quick 60fps). Each had a completely different playstyle and goal, but in the same levels. Not to mention the three character classes: Marine, Predator, Alien. Tapping into some of the more special features of the Jaguar at the time–very special when compared to the systems out at the time, the Genesis and SNES among them–the AvP had photo-realistic graphics, a dark atmosphere, and nasty, nasty enemies roaming a complex set of hub-like levels which you’d visit again and again on your trek. Good times were had.īut, one of the true classics of the system, and arguably gaming in general, was Alien vs Predator. The first games I ever got were a Gouraud-shaded polygonal 3D shooter, Cybermorph, and the remade version of Wolfenstein 3D. When I was young (so much younger than today), my fondest Christmas memory was getting a little-known, little-owned game system: the Atari Jaguar.
