The final boss fight in Crash 2, the aim is to defeat him before he escapes the station. You will be chasing him on your jetpack and have obstacles in your way. The obstacles wont kill you but will slow you down if you hit them.
To use the jetpack hold RT to travel forward, and the left thumbstick to move up, down, left and right to avoid the mines/meteors.
Simply catch up to Dr Neo Cortex and spin at him, do this 3 times before he escapes and you will kill him. I've attached a video below demonstrating.
