Generation Zero is a labor of love from it's Swedish development team. I really enjoyed the game, and purchased the Alpine Unrest DLC because of it. If you can play co-op with some friends online, do so. That's where the game shines. The solo campaign can be long and tedious, but worth it IMO. There are some hilarious and frustrating game glitches (no bathrooms in homes, getting stuck behind a wardrobe, etc.) but they are manageable. If you like FPS solo or Co-Op games and you're up for something a little different, give Generation Zero a try. I'm glad I did.
