Thanks to Zapages.
We've implimented a more open-ended gameplay system where you can choose to do some side quests to find better weaponery and the such. Also, we've incorporated a 2nd ending to add incentive to play it through a second time. (actually - you play it through with a special sword that is related to the storyline.....it's brilliant).
And if that wasn't enough, we're going to have 2 online game modes with scoreboards and some downloadable content (Xbox Live only).
