Uncharted 3: Drake's Deception creative lead and writer Amy Hennig isn't one to mince words, it would seem. On the latest episode of Geoff Keighley's "Bonus Round," Hennig and a cadre of other Naughty Dog leads speak in great detail about the process of building their latest, most ambitious project yet -- in just two years. "We absolutely killed ourselves on this project. I think this was the hardest thing any of us have ever done," Hennig asserts.

Game director Justin Richmond agrees, breaking down why the project was so hard on their team, beyond the aforementioned time constraint issues. "It's a lot of things. We didn't wanna let ourselves down, we didn't wanna let our fans down. We try to do things that no one's ever done before in a game," he says, referring to the game's massive moving environments and setpieces. It's also a measure of the game being the third entry in an established franchise. "I've worked on two 'third games,'" he says, "And they're always harder ... people expect a certain level of sophistication."

Finally, the most pressure came from the team itself. "We made it even harder on ourselves I think than it had to be, because compared to the previous games, we wanted it [Uncharted 3] to be perfect," Richmond concludes. And, at least from our perspective, the game certainly turned out to be not too shabby. You can find out for yourself right now as the game launches worldwide today.
