PC Gamer reports that it has the details on the reboot, which will be a PC exclusive title. It will allegedly update with more information in a few hours, with "one very big surprise," so we'll be sure to let you know then.
The franchise has been making its return to the game space, stomping along slowly like an Atlas mech, for several years, with Jordan Weisman's Smith & Tinker obtaining the rights back in 2007. This was followed by a tease of the reboot in 2009, with a trademark dispute shortly thereafter. Since then, things have been very quiet... until now.
Update: PC Gamer notes the game will be freemium and launch in the second half of 2012.%Gallery-138077%
