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.
The different types of training and skills that one goes through at the start of the game and then you can choose your career.
This is the modded version of System Shock 2 with much better graphics and weapons and a rebalancing of the game.
One of my all time favourite games, simply brilliant.
