The following is based on Van Buren and has not been confirmed by canon sources.
Get Rid of Lingering Geckos was going to be a quest in Van Buren, the canceled Fallout 3 by Black Isle Studios. It is similar to the tutorial of Fallout: New Vegas in the sense that you are required to deal with mutated creatures called Geckos.
Phil and Sparky are damned tired of all the geckos creeping around the edges of Burham Springs. They don't want to waste time and ammo going after the creeps, but they're afraid the small beasts will eventually attack them en masse. Phil and Sparky want them dead or gone.
Stealth Boy - Phil has a bunch of heavy bear traps that can be placed in the midst of the gecko prowling grounds. Walking over a bear trap causes serious damage and usually breaks the creature's leg. Geckos with broken legs are much easier to deal with than healthy geckos, since speed is their one great advantage.
Phil complained to me about the geckos wandering around near Burham Springs. He says he'd go out with Sparky to kill them himself, but he doesn't want to waste the time or the ammo. If I can do it, he promised me nitroglycerine, nitrocellulose, and some dynamite.
Phil was glad I got rid of the geckos, so he handed over some explosives for a job well done.
I talked to Phil about using the big bear traps for taking out the geckos. He had no problem with it.
I talked to Phil about using the big bear traps for taking out the geckos. I must have rubbed him the wrong way, because he said I couldn't use them.
