Amil Parra’s RetroBlazer is an FPS built on the modified Quake engine called DarkPlaces. Currently in alpha state, the game evokes Wolfenstein 3d more than either Doom or Quake, with mostly flat level designs save for a few instances where enemies rain pipe bombs down on you from higher platforms. The camera is locked to a single plane, which makes those areas particularly annoying (the worst being a large maze in level 6). Hopefully later iterations of this project will offer more interesting scenarios, as it’s otherwise pretty enjoyable. It looks good, too.
To get the most out of the 7-level demo, make sure you enter the console by pressing ‘~’ and bind the alternate fire and dash like so:
Alt-Fire: bind “mouse2” “impulse 100”
Dash: bind “ctrl” “impulse 15”
You’ll probably need to fiddle with the controls and video mode, also.
