DOOM II was released soon after the release of Heretic - and frankly I love this game. DOOM II places you as the DOOM marine, having returned from your victory in the original DOOM only to find Earth overrun by demons. DOOM II used the same engine as the original DOOM and had a relatively small number of changes:
Now on the surface this does not seem like much - but DOOM was such a great game that the small amount of changes in DOOM II doesn't really matter - it is still a great game. And I personally *love* the double barreled shotgun. Sure it is just a standard shotgun with half the refire rate and double the damage - but it is so much fun to use.
DOOM II runs great under Virtual PC. You can find out more about DOOM II here: http://www.idsoftware.com/games/doom/doom2/ and here: http://en.wikipedia.org/wiki/Doom_II
