Jak 3

Story related and cannot be missed.
This mission is very much like Art or Facts?. You will be sent out into the desert to pick up Wastelanders, and then bring them to a transport ship. You have to stop at each of the checkmarks, one to allow the Wastelanders to enter your vehicle, one to allow them to get out. You will be given extra time after dropping off each Wastelander. After you have dropped off 3, you will be given 4 minutes, and sent to a remote part of the desert. There you will have a boss fight. Avoid the laser beams while the alien-boss thing is in the air, then when it is on the ground, avoid the tentacles while shooting or punching it. After a couple hits the boss should be destroyed, without too much trouble. After it is destroyed, jump back in your vehicle and drive back to base. You should have around 2 minutes for this trip, and it took me a minute and a half, so you have plenty of time as long as you avoid being flipped by the enemy cars.
