1 can i wear the hazmat helmet with a combat helmet? 2 what does the new silenced rifle look and perform like? 3 are there night goggles in this dlc?
1 i don't think so
2 it looks like the basic sniper rifle from NV or FO3 just with a silencer attached
3 the hazmat helmet has night vision effect, there are a number of "lobotimite headgear" that looks like they would be night vision but they don't worse yet they have a negative intelligence effect to them.
