Developer AlternativaPlatform announces plans to launch open beta testing later this summer for Tanki X, their upcoming casual MMO tank combat game that will be released free-to-play for Windows, OS X , and Linux. They offer this gameplay trailer to show off the game's Unity engine graphics, and urge everyone interested in what they see to sign up here. Here's word on the game:

TANKI X is all about fast-paced futuristic tank combat against real players. This is not some detail-heavy simulation with bricks for manuals and hundreds of statistics to memorize. Tanki X is easy to jump into, easy to play, and offers fast and furious gameplay with fully customizable futuristic tanks across a collection of exciting and dynamic arenas. By winning battles, players gain experience points and unlock more powerful equipment, making them deadlier in the arena. But in Tanki X, it isn’t just about who’s got the bigger gun... players need tactical prowess, skill, and nerves of steel to be victorious!

Players can build their tanks from a variety of parts, mounting Gatling guns, flamethrowers, and other high-tech turrets upon a variety of hulls, such as the light and nimble “Wasp” to the impenetrable “Titan”, then pit their battle machines against tankers from all over the world. Matches can be played in teams or solo, including PvP modes such as Deathmatch, Team Deathmatch, and Capture the Flag.
