There's a new co-op game on Xbox Live Arcade this week, and I'm not quite sure what to make of it. Interpol: The Trail of Dr. Chaos is a "seek and find" adventure game, similar to the CSI Games on the PC, 360 and Wii. You star as an "elite interpol agent" - though your only skills appear to be finding replica Chinese artifacts in a castle. Sorry there's no gun play here, you are armed only with a magnifying glass.
