This week brings the awaited PC launch of a pair of acclaimed console titles; Klei's Mark of the Ninja and Ratloop Asia's Rocketbirds: Hardboiled Chicken are now available for purchase via Steam.

Originally released for the PlayStation 3 in October of last year, Rocketbirds: Hardboiled Chicken is a "cinematic platform adventure game" in which players must topple a totalitarian penguin regime using a wide variety of weaponry. In addition to a 15-level single-player campaign, Hardboiled Chicken also includes a distinct 10-level co-op mode that features six playable characters.

Mark of the Ninja, released for Xbox Live Arcade last month, is much darker in tone, putting players in control of a master ninja who must evade -- or messily assassinate -- enemy guards in a series of side-scrolling stages. Klei notes that the game features optimized mouse-and-keyboard controls in addition to gamepad support.

Rocketbirds: Hardboiled Chicken is priced at $9.99, and Mark of the Ninja is available for $14.99.
