no, there are two version of AC4. But both the PS3 and 360 version are going to be completely different. I think these screens are from the PS3 version, AC4: God is Force.
The 360 title is still unknown, but it is still going to be AC4: "insert subtitle"
Nice picture, although I've never been too big a fan of mech games. I thought Armored Core 4 was PS3 only though?
They haven't shown the 360 version yet.
