A hail of plasma bolts or even machine gun fire from a hasted gladiator is not to be trifled with. When hasted, you can move and fire much more effectively. Remember, if you move faster than everyone else you can catch up to retreating people or be guaranteed of retreating yourself. Other gladiators can actually see a subtle distortion at your position if they're looking carefully. When invisible, you're extremely hard to see until you open fire, or unless you get another powerup which displays some visible affectation.
Mega health is a standard powerup that gets the job done.
When you see it, get it. Quad damage Quad damage, just as in Quake and Quake II , quadruples the amount of damage done by its user. In exchange, however, it gives its wearer a bright blue glow, which is visible even around corners, which means that other gladiators may be able to see you coming if they're expecting you. In a close quarters melee, quad damage can be devastatingly effective. In a more strategic game, quad damage users can be avoided or detected before they have a chance to open fire.
