The PlayStation 3 and Vita versions of this mission are related to a trophy named "Duck and Dodge", completing this mission will reward you with a bronze trophy.
Up ahead you can see some spyder gunners as well as multiple mantises. There are many more mantises around here, but neither they nor the spyder gunners are even a threat at this point with your current weaponry. Using whatever weapon you are most comfortable with, burn through the many mantises until you reach a dark eco vent. Use a Dark Strike on the nearby cracked wall and head through it.
Fighting through some more mantises you will reach a strange thing on the ground spawning mine spiders. These are annoying explosive enemies that are fairly fast but are often limited by the terrain in their ability to get around. You can destroy their spawn hole with a Dark Strike if you wish so, but otherwise turn into Light Jak using the light eco vents behind it instead and use Light Flight to cross the gap on the left. Past here you will have to do that again on the right.
In here there are still more mantises and a couple of spyder gunners as well. Plow through them and use another Dark Strike at the cracked wall on the other side of this area. Past the corridor there are some stone platforms that fall apart when you jump on to them, so take care. Up ahead are some more gaps which you can cross with the JET-Board by grinding on the rails.
For the rest of the level it is the same as you have been doing up till now. Mantises will ambush you, there are a couple gaps to cross and some walls to break through. Eventually you will start a cutscene, which leads straight to the next mission: "Break through ruins".
