GOW4(Playable w/o internet?)

I have a friend who wants to get a xbox one s to play GOW4 but doesn’t have internet acsess yet in his new place,so should i tell him to wait to get the system and game or can he still play the game,before he gets internet service?I know updates are common for new games,does gow4 need a update to play properly?AIso what can be done with it w/o internet?I have this game myself but i had internet when i got it,so i’m not sure what will happen if you don’t have internet at the start.Thx…

Campaign works offline but that’s pretty much it.

Playing on LAN as well.
