Is there a sniper rank? What does he have?And where is a wiki for the game?

There's an infiltrator in the game, specialising in stealth and sniping. He uses mines, not C4, but clay mores and proxies and he can hack terminals for ally use.

They have a cloaking ability that recharges when you don't use it.
They start out with sniper rifles but can also use SMGs.

They have the lowest health and shield and their cloaking doesn't make them fully invisible. If you run or sprint while in cloak, your outline shows. If you crouch and stay still, you're nearly fully invisible.
