Really underrated game, with a nice story. It has features that are really unique for a game this old and the pacing is perfectly ballanced. The secrets are well hidden and sometimes it takes a while to figure out what to do. Therefore it takes out the speed a bit and makes you think from time to time which I personally like. Gameplaywise it is smooth and I didn't encounter any bugs so far. Also this was made by the FPS-Godfather himself, John Romero. A must-play for true gamers and FPS fans.
This game is legendary! Besides beeing the beginning of the DOOM series it is a major milestone not just for the whole first-person shooter genre but for video game history. The gameplay is way ahead of it's time with smooth movement and simple yet percise controls! The soundtrack is nothing short of a masterpiece that still gives you chills all these years later. If you consider yourself a video game fan or a gamer it is a crime not having played this timeless classic. Keep ripping and tearing until it is done!
