New sniper rifle is the bomb. It looks slick, it sounds amazing on full charge, and the kill icon/sound effect for multi-kills is amazing, although you have to be moderately close or the be the victim to really hear it well. I find it works best with SMG, otherwise you are such scout bait it isn't even funny.
It's really, really good. Only real downside (because come on, tracer rounds aren't that much of one), is that you can't plug away at people without a scope who are covered in jarate, which is a sizable drawback. Jarate is great even if you can't rely on noscoping, but, again, I recommend running SMG with this.
My brother sent me the revolver and the shotty, but I haven't really used either yet. He said both seemed pretty meh compared to Enforcer(or Amby if you are using default watch) and compared to default shotty.
I'll have at them soon enough. I haven't heard much at all about the Short Circuit.
