Tip..at that part the cholos come from 2 or 3 places...1 is from the entrance in front of you and 1 or 2 from behind you...if u stay still u will die beacuse they will surround you..what to do is run straight in the beginning to outside the entrance and kill all the cholos and the spawning ones there..now u can take cover behind the wall of the entrance so that the cholos from behind cant get u..dont worry about lance he'll survive..now poke out and kill the other cholos 1 by 1
