BLOOD!, ZOMBIES! OMG I LOVE THEM! - Dead Island 2

Yager and Deep Silver made quite a stir at this years E3 with Dead Island 2 and yet again they managed to make more noise again today /last night when they revealed this new Dead Island 2 Gameplay trailer as this time around it is actual in-game gameplay…
Ok, so the question is, IS THIS REALLY INGAME? or is it just pre-rendered with the engine as i like many others have reacted to this trailer..it looks bloody awesome, time will tell i guess but i am sure we will see more of this game the next few days at Gamescom?
