Here are some ideas from me i hope you will add it
1. Player already give 50 xp ( add that they give 50$ ) for some player really a must have
2. Donators have a higher chance for getting over 300$
3. Make the old Recoil that the gun again down
4. Killing Zombies give 20xp and 20 dollar - Maybe already ingame idk
5. Item crates on maps like zonewar and other maps for getting some stuff in pvp like ammo or meds
6. new Attachments like ( german Zweibein ) idk it in english
7. Server with Ego only
8. more zombies for better farming and more survival
9. New Zombies like in iss screamer no speedys
10. make that the attackments stuck on the guns that means when you get killed that the attackments still on the gun
11. Selling guns etc
12. New Spread
13. No locker mag weight
14. New Guns and not the guns from ISS New Beginning
I Hope you will add some features i really want the first feature
