JANUS Series

The Janus Series is the third anti-zombie weapon series to be featured in Counter-Strike Online after the famous Skull and Balrog Series. Similar to the Balrog weapons, the weapons in the Janus series were developed by Aegis Institute and built to combat zombies.

Overview
The weapons from the Janus series deal fatal damage to enemies with specialized technology implemented into them. Known as the Janus Transformation System, the weapons are capable of firing unlimited rounds after activating the system. The new system is also incompatible with the previous Skull and Balrog weapons. However, unlike the series' predecessors, no new cartridges were built for the weapons, thus allowing weapons of their same caliber to share their ammunition.

Do note that if the weapon's Janus form is not used when it is ready, the weapon will return to its original state after a certain amount of time.

So far, there are 4 weapons under the Janus series: JANUS-1=
