The guys are eating them, or just getting sick from proximity. If killed, the salvagers will stop soaking up rads. Once the lizards in their camp are killed off, they can start using Rad-Away and similar drugs to stay healthy.
Character type completion breakdown
Any character can kill the lizards, they're not too much of a threat. Avoiding their bite is the tricky part, which means....
- Stealth Boy - Should snipe them from concealment, or
- Combat Boy - Can lumber out in big armor.
