I cannot believe I've never seen this topic before!

I'm thinking mutated birds...big bastards that could pick you up and feed you to their 6 foot young. and they fly at in dependent heights, not like boat fly's how they fly at a relatively constant distance from the ground.

or maybe...well, not really monsters, but more human enemies, more then just either raider and enclave, like different raiding clans (I think that's what they did if FO and Fo2, those three clans) and some may be really smart, energy weapon users, and others are strictly unarmed, because guns are for cowards. and more groups too, and more atmospheric towns...w8, I'm gettin really off-topic, I'll stop now.

okay, one last thing, I really think thresh-hold should be re instated into the armour stats system, it's retarded that a BB gun can eventually kill someone in T-51B

Please use the FO4 Speculations and Suggestions topic, thanks.
