I have tried all the endings and every dialog option on both the Xbox 360 and on the PS3 and no matter what I do the white legs do not under any circumstances respawn.
Even if you do the evacuation option the white legs left in HH once killed are gone forever. There might be some left at three marys but after you kill those jokers they are dead FOREVER.
Why is the damn rumor that they respawn still floating around the internet? It is bullcrap the white legs will not respawn (short of having the game on the computer and using the geck)
It is a damn shame that the developers did not allow the white legs to respawn what the hell were they thinking. There is a huge lost opportunity for a continuous Zion warzone that would have made going back to HH both fun and profitable but NOOOOOOOOOOOO.
I hope to any god that will listen that OWBs and lonesome road have respawning human enemies to battle against forever. I am sick to death of hunting and killing CL, raiders and fiends I have killed hundreds of them. It is sad I almost fill sorry for the daily ass kicking I give them. I have tried out every weapon on them.
The only plus side is that HH has respawning creatures so in effect Zion is a damn forever safari of big dangerous animals. So at least my character has a place to go to hunt when he gets fed up with cleaning loser CL, fiend and raiders blood off his armor and weapons.
Please let OWBs and LR have respawning human enemies
