The PlayStation 3 and Vita versions of this mission are related to a trophy named "Ex-plorer", completing this mission will reward you with a bronze trophy.
A pretty straightforward and linear area, you'll soon encounter the new sneaky manta and gekko enemies which are both easily killed by the Beam Reflexor. As you move through the area you will encounter grunts (also an easy foe felled by the reflexor), many more manta and grunts up ahead until after a walk you go down a large elevator (with a light eco vent) and meet another new (from Jak II) enemy; the fodder. These tend to live in large swarms and are easy prey to one fully charged shot of the Wave Concussor.
Kill the fodders here and a rat will appear, then proceed to kick the animal into the nearby 'hamster wheel' to activate some machinery which you need to continue. You will have to do this a couple more times, kill the fodder enemies, then kick rat into hamster wheel to continue to repeat the last actions.
