Anyone played Portal to the 360?
Well, Narbacular drop is a game thats more or less based on it. (Gameplay wise)
Yet the bad thing is the graphics, not great, but bearable.

This game was created by the same team that brought you Portal. It was their project for UNI. The people at Valve liked the idea and gave the team jobs at Valve. Yes they,along with the help of Valve, are the creators of Portal - a great little game and rumours are that they are creating a complete Half Life2 scenario around it.

It is worth a download if you,ve not seen it before.

Nice upload !
