It's zero hour for Zero Hour, as this tactical, multiplayer first-person shooter from M7 Productions and Attrito is now available for Windows on Steam. The launch follows a very successful Early Access run that shows a "very positive" rating based on over 25,000 reviews. The Update 1.0 Official Trailer crashes the casino party with a hail of gunfire, offers a lot of English subtitles for non-English dialog, and introduces your canine companion that you will raise from a gentle puppy into a full-fledged dog of war. This post has the details on the official launch. Here's the game's description:
