max lvl cap lvl 30
new perks *including one that revives dogmeat as a puppy when it dies*
more weapons *including a morter like weapon and the tesla cannon
more armors *only one mentions atm is hellfire enclove powerarmor but it also says new armors at the side*
BUT MOST IMPORTENTLY is when you finish the game you continue the game from the reactior *apart from if you left it and it blew up *option 1 doesent kill you and you wake up 2 weeks later at the cathedral and option 2 i guess has no redioactive water but almost everyone dies*
another thing thats good is all your quests you did before it will make a diffrence in the exspansion apparantly *mabey if you give the dying thing to that tree the forest is dead?*
all i know is im gonna get this since it looks good
