It's called Gamma Frontier, and Avatar calls it the biggest expansion since the game went live over 18 months ago. Player corporations will be able to build home bases, launch industrial projects, and colonize the new Gamma islands (not to mention defend them from invasion-minded players).
The expansion also features extensive new terrain-shaping abilities. Avatar has given players full control over the land, including the ability to form hills, dig holes, and level the surrounding terrain as they see fit. Due to complications with pre-existing systems and landmasses, the terraforming capabilities are available only on the new Gamma islands (24 in total). Click past the cut to see a brief video of terraforming in action, then head to the Perpetuum website to read all the expansion details.
