Enforcer - 1
Bow - 3
Explosion Expert 1 - 1 (Those bombs add up the parts)
Crafter 2 - 2 (I can't be hanging around making stuff when there's killing to be done)
Reviver 1 - 1 (You'd be amazed how many people get downed in this game)
Covert Training 1 - 2 (Just for the free shiv, I always forget to make them and end up getting noobsticked)
Machette - 3 (Best purchasable to go with the bow, stop rushers DEAD)
Saying that, I've been getting owned all day. Some really good players and some really crappy enemy spawnings, plus one guy who took a molly at his feet and didn't even blink. Go figure.
