Its like they took the game and injected steroids in it and you really feel pumped when you play it because is became so much more energetic.

Every espect of a modern 3rd person shooter have been implemented in this game while still maintaining the old school familiar feel of the game we use to know - hugh amount of weapons, secondery fire for each, grandes, lots and lots of enemies blood splatters and body parts flying around after getting shot with a rocket launcher.

the new version has added vehicles, dual wielded weapons,  new visual effects and much more

highlt reccomended for any doom fan and even newcommers
