In this pop-up video treatment of the God of War III trailer we get a few new tidbits of information.
The trailer was shot in-engine and was edited down to be much less violent than the video game; expect spilled entrails in the game itself. We also learn that God of War III will be able to handle 50 enemies on screen at once and that the polygon-count for Kratos is four times more than it was in God of War II.
Check out the full video for a few more details.
