can't find him anywhere at all, and i have a note for him. im guessing he might be dead... is there a way to revive him ps3 version?

Isaac for the gunrunners?

Did you check his house in the cluster of houses East of the gunrunner shop? Sometimes he gets 'stuck' in there until you go inside.

well, i ran into him earlier in the game to see him fighting with fiends on one of his random strolls, i saved him leaving him with about 8-10 bars of life. i did check the houses and the area's surrounding for an hour looking for friendly blips on my compass to no avail. i have not found a body anywhere, and i would like cheaper guns and ammo for the dude in Camp McCarren. i played it through before the latest major update and got screwed with the legion being neutral and getting attacked when i got to ceasars tent. so i had to start from scratch... i already have 100 cans for the next task... and the gun the ncr gives me as trade for turning the supply guy in is not worth it.. i hope a patch comes out were they do not die, cause that ruins the game for people when its part of a quest or mission to find out they are dead and you could not help but to find out in a manner such as this. they could at least replenish the health after a fight like boone and all the other followers...
