No... I am not always right.
Sometimes I forget that people can't understand what I am on about.. So here is a full explanation.
When DoD was in build mode, they needed to simulate a large amount of black smoke and fire..
Burning Tanks and so on...
So some kind soul coded an Entity for them. (wether it was an HL code hack that already existed, or something to do with DoD's spirit code, I am not sure.. My guess is that it was already there.)
That entity is
cycler_wreckage and available for all to use.
It is not a sprite!
