The vortex shield is a Titan tactical ability, that "catches incoming projectiles, and projects them back". For the purposes of the vortex shield, what counts as a projectile or not, i.e. Is the charge rifle a projectile?

The charge rifle shoots a beam of energy so there isn't a projectile. A projectile is a physical object which is projected.
