From Soul Brother developer Superflat Games comes a much more somber side-scroller. Lone Survivor is about just that: a guy in a surgical mask who is the only known survivor of some unspecified disease. As he tries to escape from the desolate city, he must sneak past, fight, or otherwise deal with a series of threats that he's not even sure are real!

If isolation-induced hysteria sounds like your idea of a good time, you can try Lone Survivor for free on Kongregate, and then buy it on both PC and Mac for $10.
