Havok Explosion
Not to be confused with the Havok game engine.
The dreaded Havok explosion (name comes from the Havok game engine), also called a "havok", happens often when you rip off an external powered component, like pistons or motors (look at The Boxer or Ripblade).
It creates an invisible anomaly that behaves like a landmine: when you come close to it, you have a big chance to be tossed randomly and apparently with no reason. Sometimes, the same component can create several havok explosions.
Havok explosions range from a small push that will unbalance your bot and raise one or your sides, like if you were flipping a heavyweight with a Snapper2, to reaching the ceiling in 0.2 seconds.
Extremely annoying (if unfair) because it can make you lose easily, or funny (but still unfair) if the other bot havoks.
How havok explosions can ruin a match...
ALSO: Havok explosions can also occur on bots that are extrememly stacked with snappers or servos, even without losing a motor. The simple process of turning can send your bot flying.
