Killa earned his reputation back in the days of the Contract Wars, when he and his crew took over the ULTRA shopping mall. For most locals, that mask with the three stripes means death. For a select few, it's a reminder of wild dubstep parties somewhere on the city's edge.
Killa uses a light machine gun or other automatic weapon to suppress the enemy, while lurking from cover to cover, getting closer to his target for the final push. During the assault he moves in a zig-zag pattern, uses smoke and fragmentation grenades, and relentlessly suppresses enemies with automatic fire. He will follow his target large distances out of his patrol route, so be sure to run very far to get away from him if he has locked onto you.
It is recommended to avoid being spotted by Killa. He has multiple grenades and is generally accurate with his bursts. If you are close to him he will continuously push the player and relentlessly hunt them until he ambushes and assaults them. It is best to attack him with high-penetration ammunition such as 5.45 BS, 5.56 M995, or 7.62x51. Without proper ammunition to kill him, shredding his 6B13 M to low durability or firing solely at his legs are both appropriate, albeit more risky, strategies. Grenades generally won't work to kill him, as he is a highly mobile fighter and will rarely be pinned down long enough for a grenade to stop him. If fighting him with a teammate, attacking him from two different directions and peeking cover is a sound strategy, as he will continue to suppress one of his opponents while the other can safely return fire.
