SouthPeak and Firefly Studios have announced that upcoming castle building strategy game Stronghold 3 will now be released later this summer.

The game's release window has been pushed back to enable a host of new features to be added to the game.

"We want to make sure fans get the game they want and deserve," said Stronghold 3's designer Simon Bradbury. "Although some may be disappointed the game isn't coming out as soon as they expected, we're sure they won't be disappointed with the new elements we're adding to the franchise, to make this the best Stronghold yet."

Stronghold 3 promises to offer night time battles, improved multiplayer, cutting edge physics and a stunning graphics engine.
