I'm hoping to see the return of the pump action shotgun and maybe a reverse pump action shotty. A bullpup style rifle and a actual beltfed machinegun as well would be great also. Possibly the return of different ammo types.
Attachment wise in hoping attachments can be added and removed and swapped. Also more attachment types like underbarrel weapons like a underbarrel railgun. Also different scope types that can be swapped. Also front rifle grips that can be added and maybe a bipod.
Combat wise in hoping to see maybe prone added and maybe a small form of cover system and sprinting.
For useful items in hoping to see cryo nades or flashbangs and maybe a riotshield.
Easter egg wise im praying for Beth to do some slight advertising in there game of there other ips similar to how valves cameod portal in skyrim. Like maybe a blaskowitz npc or a weapon from wolfinstien.
