The developers of Assassin’s Creed have always boasted of their game’s high level of environmental interaction.  They claim that every wall, object, or person in their highly anticipated Xbox 360/PS3/PC action-adventure game can be scaled, moved, or shoved.  And now here’s the video to prove it.  Watch Altair (the game’s featured assassin) try to escape the city’s guards by running, climbing, and jumping all over this Middle Aged playground, and kindly ignore the futuristic glitches and flashes that hint at a more mysterious storyline that Ubisoft will not divulge.  Gape at the mind-boggling geometry that for once actually does permit the level of interaction promised by its enthusiastic creators.  Raise an eyebrow at the anachronistic Hans Zimmer-esque musical score.  Breathe a sigh of relief that this long in development game looks like it could conceivably hit that once nigh-unhittable November release date.
