no video. but good explanation on what to do: load up mars patrol go to the valley of the kings head to the giant moving fortress used in the valus ta'arc strike kill all the enemies in the area quickly. very quickly. use a super perhaps. sword helps. to the left of the entrance to the fortress is a small cliff walk towards it. jump on a little outcropping on it. any of them will do. your location should be near another small cave. don't worry, enemies won't spawn from this one. look towards the entrance to the fortress and a little to the right. you are looking for a small cave enemies will continuously spurt out of this cave. no other enemies in the area will spawn. have fun with your blue engrams. (I got one blue engram in 5 minutes, another in 5 more minutes) please bump and like this post so everyone can see! :D
