One of the most amazing and most memorable games ever created and yet so old by today's standards. 1. Graphics: While not the best today, were considered amazing back then. The hell knight, imp, cacodemons, and all others have such classic images that no one can ever forget them! The graphics are so classic that no one can do anything but enjoy watching the cacodemon's face grimace as you pummel it with a chaingun! 5/5

2. Sound: The most distinguishing part. Try to play the game without sound, you just can't enjoy the experience. The moans, the roars, the howl of the Cyberdemon, and not to mention the creepy background music, are all classic and well done. 5/5

3. Gameplay: This portion is done so brilliantly. Four long and intense episodes, and not to mention four of the most amazing and memorable bosses ever encountered! The levels are incredibly creative and, from green ooze to teleporters, there is always a challenge. The keycard idea is genius and adds strategy to the game. This is definitely THE first weapon setup that can ever be remembered. From your callous fists all the way to the mother of all weapons, the BFG, the possibilities are endless! 5/5

4. Difficulty: It will range from incredibly easy to incredibly hard. Both the ingame difficulty and the difficulty you set it at play a factor (there are 5 difficulties you can select before the game). NIGHTMARE mode is a genius idea, not only providing you with most damage inflicted, but monsters will even respawn! Whoever says old games aren't challenging never tries out EVERYTHING the game has to offer. 5/5

5. Replayability: After playing through all the levels, you will still want more. The urge to destroy the demons and utilize such creative weapons will carry you on to playing this game for as long as you can before something else takes you away from it. And of course, who can forget the memorable cheat codes embedded into the game. Infinite ammo, god mode, level warp, and others will keep you experimenting forever, always finding something new. 5/5

6. Story: The stranded marine, fighting his way through hell is the simple set up that carries you through everything. The narratives at the end of each episode sets you back into the story, and will prepare you to fight hell once again! Simple and effective. 5/5

Final Verdict: 30/30 Recommendation: PLAY THIS GAME!
