Externalized accuracy multipliers for crouching and walking
Seperate accuracy and spread values. Am I the only one who thinks it's weird that shotguns have a significantly reduced spread when prone as opposed to walking?

Variable projectile and paratrooper speeds for calls.

Externalized ranks

Support for different models based on rank

Support for firing delays.

Support for weapon failure, where the weapon can stop working or kill the user
Support for interruptible cycle animations and reload animations
Support for seperate corpse models. Playing with a high body cleanup threshold is really difficult

Support for reduced rotation speeds for infantry weapons

I suppose these two suggestions are the same, or at least in RWR they would be same. There are stance multipliers for prone, crouch, still and walk which get blended with weapon accuracy, and spread controls the maximum how much the bullet velocity vector can get offset due to inaccuracy

There is no rotation speed.

I'm sorry I was unclear. I was referring to the pellet spread of shotguns in this case. Currently, when prone, the pellets spread much less than if the player is walking. What would be more realistic would be a shotgun that had the exact same pellet spread at all times. When the character is moving, the axis of the pellet cone would point slightly away from the crosshair, when prone, it would point closer to the crosshair. This would preserve an accuracy difference without actually having to change the spread of the pellet cone.

What I meant was support for infantry weapons that force the player to turn slowly while standing or crouching, like a vehicle turret or a prone player.
