As far as I know, everything is serversided.
This is bad, ofcourse, BUT, it can still be used for hacking

My idea is, to somehow make the server send enemie player data along your own data!
This means, you could display postition, heal, speed, ammo, direction, basicly all data you would normally have access to.
In further stages of this hack, it might be fun to take a enemie players plane over

That's my idea, thought of it while eating a egg and drinking tea.
Anyone knows if this is possible?
