I'm on my 2nd time through the game and I am doing the realism mod and hardcoe mode and I am about level 5 or so. I'm exploring toward Vegas and I came across a pack of Cazadors. I killed them, then one came out from left field and was in a fight with a couple Secure-atrons and I noticed that one of those now dead Secure-atrons was poor ol' Victor. I'm wondering if this is going to affect my questing travels or not? I don't know if I would consider him an "essential" character or not, but from my first time through, I remember running into him many different times before I actually got to Vegas.
Also, why in the hell were Secure-atrons roaming that far out in the empty desert?
