The fifth of five NERO research sites in Crater Lake, on an island. Reaching it takes one of the longest bike jumps in the game. Max out speed and Nitrous at Diamond Lake before you try it.
You get there with a bike jump off a ramp. Fit Nitrous and the best engine you can afford, then hit the ramp at full speed with boost. Save first, because a short jump means a long fall.
A NERO Injector and an intel recorder. Pick the boost you are shortest on: Health if you die to Hordes, Stamina for riding out fights, Focus for slow-mo aiming. NERO checkpoints hold injectors too, so check both on your map.
