GZDoom - 2.3.1

GZDoom, the modern Doom engine, lately reached 2.3 and 2.3.1. The latter is a smaller bugfix release while the former adds a whole slew of new features. The engine now has official scripting support, support for screen space ambient occlusion, an improved IWAD picker, many rendering improvements, etc. If you want to play Doom or any mods based on it with some modern graphic effects, look no further!

Another cool screenshot taken from the GZDoom forum. Note the reflections and the map on the wall.
