Hi nelson I want to say that in unturned 4.0 there should be holsters and you should be able to carry atleast one weapon without a sling https://www.google.com/search?q=weapon+sling&safe=strict&client=firefox-b&tbm=isch&source=lnms&sa=X&ved=0ahUKEwjn4tqTks3fAhVGWBoKHYvMBKIQ_AUI3QEoAQ&biw=1366&bih=693#imgrc=67gtoVmltzYpiM: and you should have an actual level for strength and you should be able to increase it by carrying max items or doing push ups ,pull ups etc . and that should have an impact on melee and how much you can carry whitout getting tired . I know there is a level bar but what i said can be a second option , and there should be emp’s .
Bases should be interactive for example , you should be able to have more options to build . Building options : fortified garage door , trip wire cameras , electric barebed wire fence . You should be able to make bunkers with a shovel but in the bunker you need a vault hatch , metal ceiling oxygen filter etc , and fake bushes where you can put a bunker hatch or fake trees with turrets inside them . 
sorry i im asking for too much , i just like to have more interactions with my base .
