Jasper Byrne's acclaimed side-scrolling survival horror title Lone Survivor is now available for purchase via Steam for Windows and Mac.

Released last month, Lone Survivor is a dark tale in which the player's character must scrounge for food and fend off mutated creatures in a disease-ravaged city. Drugs found throughout the town can reduce the need for food and sleep, but rely on them too much and your character will suffer from hallucinations.

Lone Survivor can be picked up for $7.99 during its launch week, and will be priced at $9.99 afterward. A free demo version is available at Kongregate.
