Cloaking

"Turn invisible for a short time."
Used widely by skilled players to sneak attack on other people. The attack, combined with the HW-10 Machairodus can be an easy way to avoid fire. When coupled with a Black Mamba, this ability can make a sniper a huge problem for your team if a player with these things is on the opposing team, if but they are on your side, it guarantees a kill.
