Petroglyph has recently announced their next real time strategy game: Grey Goo, which should be published by a mysterious company called Greybox. It should feature 3 new factions and all the good and solid mechanisms that makes real time strategy games fun, such as base building, resource collection and a focus on macro-management rather than micro-management. The game will be Windows only originally and it should be sold on Steam. It can be played online and offline (skirmish) and it should feature a story driven campaign. According to Petroglyph, the game should be available on late 2014 and it will feature soundtracks from Frank Klepacki. For more information, head to Grey Goo's Official Website.
