"You've Been... Terminated"
With Lambda, summoned every type of sword during a single round.
All you have to do here is to hit the opponent with all of Lambda´s normal Sword summoner attacks.
5DD
6DD
2DD
4DD
j.DD
j.2DD
Remember that all of her sword summoner moves have 2 inputs and 2 hits. The achievement will only unlock if the system registers bot hits from each attack. This is easily done against Tager since he´s so big that you can do 6DD without even launching him. You don´t have to do a combo with these moves! (video is linked below)
