I can't find the upgrade guys I used the lair for a while got nothing, and going back and forth nothing, is there limits to how many will show up based upon story or something? --- Mithra 72 Paladin/36 Warrior Asura.
until you get the whipfist you can't max out everything. I maxed out claws and sword but waited an hour for hammerfist upgrades but didn't get any until getting the whipfist. --- XBOX360 GT: AlphaUltima
I was wondering about this. I was in the Green Zone and waited to do Lairs until I got Bio Bomb so I could get as many upgrades as I could. I have Claws and Tendrils at 3, sword at two, and I didn't get a single upgrade. --- "Blanka, Zangeif, Chun-Li, Guile, E. Honda." That's Street Fighter. "Red, blue, green."
