It is essentially a rift in the space-time continuum that rampages through the battlefield, destroying everything in its path. It appears as a giant whirlpool of bending time, defying the laws of physics. This devastating event has a 20% chance of happening each time the chronosphere is activated, thus making it more common than another devastating side effect the chronosphere can unleash from overuse. Vortices were generated near the device in use and appeared as swirling space-time rifts.
During the final assault on Moscow, General Nikos Stavros warned Field Commander A9 that using the chronosphere could produce "unknown side effects". It's assumed that this vortex is the side effect that Stavros was warning the commander about.
In Command & Conquer: Red Alert there is a 20% probability every use of the Chronosphere will create a vortex. A vortex moves at speed 10 and deals 200 damage per "shot". It searches for targets within a range of 10. A vortex's lifetime is variable. It is possible to make a vortex collapse by sending some units into it.
There's a moderate chance that some units destroyed by the vortex will reappear later.
