Crash Bandicoot 2: Cortex Strikes Back - OPM Trailer

This trailer comes from an old Official Playstation Magazine demo disc. There are lots of early elements, including a different logo, the presence of the Crash 1 HUD, alternate routes and the regular spinning animation with the jet-pack. It also shows footage of an early version of Sewer or Later.

Kudos to Keiji Dragon for the trailer and information.
