I've been discussing it and there is a lot of things that are beneficial about games in development, one of them is new content ideas. Here's some I've thought of;
-Explosive weapons are rare so what about grenade launchers, RPGs or C4. Possibly AT mines.
-Those large trucks you see around would make good transports and could have an inventory.
-Maps: How about a winter map that requires you to wear coats, get in cars (Which require heating on that takes up fuel) or stay indoors to not freeze to death.
-possibly a button that can possibly "surrender" and request a team up.
-Controls need to be tightened up to make aiming and getting through doors easier. (Basically, the controls should be more like other FPS games.)
-Move the roll bar on the dune buggy.
-Remove or lower the auto-deploy on parachutes.
-A ton of new guns such as: G36, Desert Eagle, AA-12, Barrett 50.Cal SR, Mounted Machine Guns?
Feel free to add suggestions or share to the Dev team.
