Counter Strike Online Wiki

The BALROG Series is the second Anti-Zombie weapon series to be featured in Counter-Strike Online after the famous SKULL Series. However, unlike the weapons from the SKULL Series which were developed by the Government, the weapons from the BALROG Series were developed by the newly formed Aegis Institute with the same purpose of combating zombies.


The weapons from the BALROG Series deal damage to enemies with the unique technology implemented into them, known as Balrog Charging System, where the weapons cause explosions and an increase in damage after continuous firing. Along with the weapon's technology, Aegis Institute had also created a new 'specialized' type of ammunition, known as the AHE (Aegis High-Explosive).

So far, there are 6 weapons in the BALROG Series:
