here is a question i cant find awnsered,
1) do you need to do waves 1-50 to get the acheivment like in GoW3 for the medals for the difficultys?
2) do all 1000 Kills have to be in one Guerrilla Mode Match?

if so its stupid as you cant see how many you have killed so far, i must have done office with 1 friend from waves 1-30 and lost count on kills as it doesnt tell you how many kills youve had
