This is legitimate inquiry. I've seen two kinds of invisibility. I thought one was skill, one was hack. But I couldn't find "invisibility" ranked. In one instance, one player was visible via his team color ring in CTF, but player himself completely invisible, only the team color ring and player name. I was like... huh???? How do I get that? In another instance I rushed to rev station and was hoping to rev blood and suddenly I got crit and was killed. Absolutely _NO ONE_ visiibly near me. Doubt it was ping as my connection was good at that time. I usually don't PVP when my connection sukky because no point.

Thx.
