Imagine an action setpiece from Uncharted extended for 3-5 hours.
The sort of game that's very blatantly a "look at our physics engine" game. Not very good but it is interesting. I think the water physics are genuinely nice, it is funny blasting a barrel then watching water knock an enemy around, but everything else in the game feels undercooked. The cover system particularly sucks. The story just stops too since it was meant to be episodic but flopped and took the studio with it. Unfortunate nothing became of this game's engine, it could've been nice.
