Hey guys, just thought I'd point you to an old site I used to maintain, the Ghostbusters Fan Forum Arcade. I've got a page outlining the game pretty completely, though I meant to scan in the map for the Liberty level and never did (otherwise you'll never know where to go). Anyways, check it out, and if you look at the other pages of other GB games, remember, this site is *old*! I didn't know anything about design whenI made it. i'm planning on remaking the whole thing this summer though, so hopefully the Arcade will look better soon.
