Martian technology at it's best.  The Cyborg is another robotic warrior, with only the exception of his right hand, which appears to be that of some type of alien.  The Cyborg surveys the Arena with his large eyeball, mounted on a telescopic tube.  There appears to be at least enough living tissue to necessitate the use of a breathing apparatus mounted on it's back..
MARTIAN CYBORG
	Before the creation of the Arena, Earth and Mars were at war.  These infantry soldiers from the United Resistance Front(URF) were the only thing keeping us humans from walking around speaking Martian gibberish.  Fiercely loyal to the cause, and hardened from years of combat , the URF Infantry are some tough customers..
URF INFANTRY
	The Brainlet is a Martian experiment gone bad.  These little bastards are not only small and hard to see, but they are noisy as hell too.  Don't be fooled by their diminutive stature - they have telekinitic abilities that make them worthy of any opponent..
BRAINLET
	The single most intimidating opponent in the Arena is the War Machine.  Resembling a meat-grinder of sorts, and piloted by a demented little Martian, the weaponry is housed within the lower portion of the unit, making it difficult to determine just what firepower they may have.  .
MARTIAN WAR MACHINE
	Last but not least, is the Martian grunt.  These little guys were the original combatants in the Arena, and eventually gave way to their more powerful Enforcer siblings.  Don't underestimate them however, as they are just as nasty and intelligent as their big brothers.
