The following explanation will replace the current explanation of the Nex on the official Nexuiz Wiki.
Previously theorized to have magnetically fired antimatter at supersonic speeds, a brilliant physician noted the inherent factual flaws between such theory and actual effects in practise. The most viable explanation as of yet, states that the Nex is a relativistic in nature, magnetically slinging a minute number of charged particles at a velocity approaching c. At a relativistic velocity, particles are capable of catastrophic destruction of entire molecule chains, emitting a burst of high energy radiation in the process. The trails have been best explained as the result of intense friction caused by relativistic particles, instantaneously converting nearby particles into quickly dissipating plasma.
