whoa, this is the Chaos Crossbow from Chaos UT2: Evolution
Info: This Crossbow has been a weapon of many Tournament Fans, but now it is a deadly weapon taking on the Tournaments of many others
Ammo Types Usable: Standard Bolts (Grey), Inciniedary Bolts (Red), Fragmentation Bolts (Orange), and Toxic Bolts (Green)
NOTE: Stay away from Crossbows when the Arrows are Poison, as 2 can kill you easily
It still packs a punch, especially with those toxic bolts.
