Re-DOOM is a remake of the classic Doom game intended to replicate the engine from the game. The game is played using the standard W, A, S, D. The mouse lets you choose your direction, and the top number keys scroll through available weapons.As soon as you begin, you are immediately reminded of the original Doom. The big difference is that you have access to a lot of guns early on. The BFG, shotgun, plasma gun and more.Find the key card to exit and go to the next level. Watch out somewhere in the game for a hidden switch that will reveal all the cheats.
