The official Just Cause 2 thread.

I I never did play the first one.

With some of the most incredible emergent action sequences seen in any game, Just Cause 2 frequently features moments which simply defy description. Moments where the physics, gameplay and AI all come together to create an over-the-top stunt or spontaneously chaotic scene of carnage players will want to watch again and again. By activating Just Cause 2’s video capture feature, players will be able to automatically record the last 30 seconds of gameplay directly to the PlayStation 3’s hard drive and upload to YouTube.

BASE jumped from the highest bridge in the game? Captured. Jumped out of a jet fighter and crashed into an oil rig? Recorded. Parachuted off a cliff onto a passing helicopter, laying waste to a military harbour with missiles, before ejecting, skydiving down through enemy flak, grappling soldiers to passing aircraft, leaving nothing but the smoking remains of the military might? Saved, uploaded and published for the world to see.

Also available from the in-game menu is a 10 minute capture feature which allows players to create more detailed and planned presentations. Gamers will be able to capture and share in-game mission walkthroughs, create online speed-run competitions, direct their own South East Asian-inspired Machinima and more, with the best YouTube videos linked from the official website allowing users to vote on their favourites, with prizes awarded for the best of the best.

oof
that's some sketchy lookin AI.
not real keen on some of the canned animations either...but whatev
i'll be eager to check out the demo to see how it feels.

reminds me of the lovespawn of a 3-way between Pursuit Force, Mercenaries and Spiderman.

and don't know if it was mentioned in one of the links above, but the PS3 version has an exclusive video-capture mode with direct YouTube upload.
SquEnix sez:

So the video capture feature will only be on the PS3 version?

yes
video capture mode is PS3 only
