FastForward V 2.1 Mod
With the FastForward you can screw up the time factor at short notice.
Operation: In order not to trigger the whole thing accidentally, the acceleration can only be started with a key combination (CTRL-R) in the first-person perspective (get off!). The whole runs also only as long as one the keys pressed.
In Multiplayer you can change the time acceleration, of course, only with Admin rights.
