Under Siege built exclusively for PSN with in-game level editor

There's a new video for Under Siege posted after the break showing how Seed Studios created the RTS using the in-game level editor.

"One of the major features of Under Siege is our in game editor", states the official developer blog. "We’ve taken a page out of Little Big Planet’s book here and decided to not only include a fully featured editor, but also to create all the included game content using that same editor.

"You will be able to mold the terrain, define terrain properties, adjust water, place props, adjust lighting, create triggers and cut scenes, and essentially create a whole new game if you feel like it.

"Having built all our levels using a PS3 controller led to constant improvements in both the interface and the control scheme so that our level artists wouldn't feel constrained by the input device."

No word yet on a release date. More through the link.
