The Chronicles of Riddick: Assault on Dark Athena

After you're captured and put into cryo-sleep, you'll find your way to escape your exercise room and eventually be on the run yet again from the fuzz.

You'll come to a point where you open the corridor doors, and then backtrack through the underground vent system all the while combating those annoying little drones. As you lift your self up into the corridor, you'll see a pair of those posh Portal-esque white mechs at the end of the hall. Simply pick them off with your pistol from a distance, and then proceed.

You'll then come into a kind of 'stock room' for these white mechs, fear not as they're inactive. Anyway, at the far end of this room there will be the four-legged beast you're boarding. So hop, skip and jump your way there and press Y to activate the scene where Vin Diesel does what he does best - the improbable.

Pop goes your achievement, and thanks for reading!
