Ah, I've not gone to the combat zone yet, that was my next task. I keep getting sidetracked by other stuff, it's ace.
My game bugged yesterday, so it wouldn't notify me of gaining XP when you discover stuff. Didn't worry about it too much, although a few hours in it occurred to me I must be missing out on a shitload of XP! Went to the stats page, and noticed a number by the level up button... Yup, I'd still been gaining XP but with no notifications, I hadn't realised I'd jumped four levels and needed to grab some perks
Also, the chameleon armour (not a spoiler, it's a random leg part I got by defeating a bad guy) is glitchy as hell. It makes you invisible when crouching and not moving, however it makes your Pipboy invisible as well so you can't see anything on it!
Not sure if real broken, or Bethesda trolling hard.
If you can shoot the nuke out of his hand, it makes life interesting when he's stood near his mates
