Later on that year (after having finished both Quake and Duke3D), I went to CompUSA and picked it up for a cheap $28 (eep). The full ver felt weird at first because I wasn't expecting a Leonard Nimoy-ish to talk to around the beginning, and most of the voices sound different than the teaser, but I got used to that, loved it till I got stuck in the sewers back then
Another interesting note, Strife seems to be the first FPS to ever use the F-expletive vocally, though.
