Are there any scripts that affect other players?

Like if you can "infect" a player. Such as give them health or infinite ammo.
Give a player money,give exp, or unlock weapons/mods. Is there a script that can do that?

you can tase/bleed out other users and more or crash their game. (or crash the whole crimenet)

if they want all the goodies they need to have a trainer themselves.

How exactly would you make other players get affected if you arent host?

there is way but its highly disruptive to the game, so not fit for release.

ill give you clue, sync states

Disruptive?mhmh I can see but is it possible for someone to make an exp for friends. I'm not much of a coder :/
