Worth the effort. I played the first couple of scenarios (i.e. the drill, etc) and was just about to uninstall, thinking this game wasn't quite for me.. and then I skipped to the 4th and last scenario which was just "Survival"... and I'm glad I did because it turns out I just wasnt a fan of the "Scavenge" scenario (yet). The game has great replayability, solid music, and pleasant sense of humor. I'll be playing this game for some time to come now. :)
