@TheSpaceDad here i go with some ideas:
- When u die or when u start the game u need to load everything, if it's possible put it to auto-load, and the inventory auto save cause imagine saving an inventory in the middle of a war.
- Air drops, like from sollaholla mod but u can randomize the group that is calling the airdrop, everyone want more guns on a apocalyptic world
- Gear/Clothes, like vests and some craftable/collectable clothes, the backpacks would need a bigger work but the vests u can add some levels that the player find on a Police Station or in the Military Base.
- Mechanic ped or building, every player will want to upgrade their cars to SMASH the zombies, and a better car will help on that.
- Seasons, like on the winter the zombies rate decrease and the snow appear. (if u put this you can also make the clothes have a utility)
- Some mods support like Open all Interiors.
- More looting methods,from cars,trash,vending machines...
- A coin to trade with the Friendly or Neutral survivor.
I know that is a hard work but this looks really cool if u add.
