Improvements to the game.
Night vision googles you can toggle on and off. Very rare item: cannot be made, you do some mission and find it on a dead red talon guy.
Weather change, the rain makes it harder to see ETc. Different zombies come out during different weather.
Improve the outposts. To wear we can fix our gear, fortify the windows, add bar wire tear down parts of the building like in fallout 4 ect. Make it something worth defending.
More survivors trying to survive out in the world. Really cool idea. When you do a mission and a survivor follows you, there is a chance that that survivor will try and betray you or kill you so you have to keep a eye on them. More dangerous people in the world. Rebel gangs that seige your base, looters ect.
The ability when you exile a survivor from you're community to execute them instead.
Also want more gun customization. Different laser colours on firearms the ability to have a pistol secondary and a main primary gun to switch between.
