adds a new weapon, new enemies, and new levels with the same amount of carnarge of DOOM! a great game!!
if you haven't played or even heard of DOOM 2 and are a goody-good-wanting-to-know-the-story-so-i-understand-the-point-of-the-game kind of person (i went a bit too far with that didn't I?), then i give a rundown on its tiny story.
DOOM 2 is set like 5 minutes after the events of DOOM and takes place on Earth, hence the name "Hell on Earth". you are a soldier who has just arrived home from the incident on Mars to find Earth infested with demons and monsters. and so now you blast the human race to freedom. end of story...
while DOOM 2 is a lot better than DOOM in many ways, it didn't add anything really new to the gameplay. the gun still aims for you, the same weapons are there apart from another shotgun, you still can't jump or look all around the room. these would've helped DOOM 2 in a lot of ways regarding improvement in gameplay. either way, the gameplay in just plain fun.
the graphics haven't changed a bit (which looked great back then) or the sound effects. there are new themes for each level but unlike in DOOM, in which the background music could be heard like a stereo in car, DOOM 2's music can hardly heard at times.
anywho, DOOM 2 adds a few new things and continues the DOOM series rather nicely. so if you've got DOOM and are getting bored of it, which most of you should've with DOOM 3, pop this in your hard drive and blast away with this great game. i can't until i get a copy of DOOM 3, yeah i know its been out for ages, i just haven't around to it with the Resident Evil franchise taking over my mind.
