I would like to see a weapon, or various weapons like this be in the game:
The rifle is quite large, so if they have larger rifles, such as this one; to help save inventory space, maybe the weapons could be taken apart. Or better yet since this game is set in the future, have the weapons fold, or collapse into a smaller, easier-to-carry state. Sort of like the weapons in mass effect. Within reason though. It would be a little ridiculous if someone was walking around with three GEP gun sized weapons. The weapons could be stored in holsters, backpacks, brief cases, ect...
Obviously, smaller arms like the two weapons shown in CP77's preview don't need to fold or collapse.
It would be interesting to see a more immersive inventory system. Rather than having a basic menu with slots, why not make the inventory wherever the player's items a stored, and possibly being able to use it in real time? Similar to quick selecting weapon attachments in the Crysis games. (this is purely an example, and speculation) Say your character is at some food vender, and you need to get your wallet out of your left pocket to pay for the food, rather than going through a menu, the player presses/holds a key/button on their keyboard/gamepad, and items lists pop up next to the character's pockets, showing what's in them. Then you just select the item you want, and the character has an animation of getting that item. Just an idea
