Canadian publisher Meridian4 has used Steam to distribute a number of their PC games and their next title is Tank Universal, an arcade-like action game that visually has elements of Tron and the original Battlezone. Developed by Dialogue Design, the game has players engaging in massive tank battles and even on foot missions and will have a number of Steam achievements to unlock.

The game is due for release on August 21, but if you pre-order the $9.99 game now you can get Shadowgrounds, the top down sci-fi shooter from developer Frozenbyte for free via Steam. Like Tank Universal, Shadowgrounds is published by Meridian4.
