DOS

Wanton Destruction

Aside from that, it's Shadow Warrior. If you want more levels, these are some of the best, at the best possible asking price. Not worth picking up the original exclusively to play this, but absolutely worth grabbing alongside it. Big thumbs up to Sunstorm and 3DRealms for releasing this for free, and supporting their old titles and their old fans. They just as easily could have thrown the disc in the trash, and you'd be missing out on one of Build's finest hours.
