Pretty much the same thing as the original, just with some nice gameplay changes sprinkled in, so read my DOOM review if you want to know what I think about this.
Never played this version-- I can't seem to find the version I played in school. But, I suppose it is the same thing I used to play at school in my free time all the time.
I mean, I am sure that this game was the shit back then, likely due to its graphical capabilities. But, nowadays, its just ok. Pretty rage-inducing, but ok.
