The randomly-generated protagonist of Void's new semi-roguelike semi-RPG Hack Slash Crawl, is often an engine: a perfect monster killing machine. All this machine can do is hack, slash and dungeon-crawl. But when you do only three things, you better bet that you can do them well. Likewise, while Hack Slash Crawl is kind of shallow, and could stand some polish, it makes for a fun little click-fest.
MAD: Mutually Assured Destruction is a souped-up rendition of Missile Command with great art by Brad Baum and clever resource management design by Nic Daniel. Shoot missiles in an attempt to intercept other missiles, just like in the classic arcade game, but with a twist: Each missile you fire garners some resources that can be spent to upgrade buildings.
