A brand new platforming adventure game has just been released from Nitrome: Dirk Valentine and the Fortress of Steam! Dirk Valentine uses similar mechanics as Nitrome's own Frost Bite. Move Dirk with the [arrow] keys and aim with the mouse. Press the left mouse button to fire the ricocheting chain gun. The slightly more serious tone and steampunk setting is a departure from Nitrome's usual fare, but the high quality of artwork, music and overall design remains the same.
