The first video game I ever played as a kid was Space Invaders & Missile Command on one of the old Atari consoles. One of my old favourite games I played on the 3do was Space Hulk Vengeance Of The Blood Angels. Then came Xcom Enemy Unknown and Terror from the Deep on the Sony PlayStation. But my two really old favourite games have to be Wolfenstein 3D and D00M.
This is one of my old favourite Stalker Shadow Of Chernobyl mods from way back in 2007, ABC Inferno. One of many things I particularly love about this mos is the HUD layout. Recently I have started to play it again and it is great fun, if you have not heard of this mod then you should check it out. This mod runs fine with patch 1.4.
