"You've Been...Terminated" : With Lambda, summoned every type of sword during a single round.
This trophy is actually quite easy. All you need to do is use each form of lambdas swords and make sure both swords come out. Each direction has two blades, both of which count for the trophy. These swords are set to lambdas drive techniques, which are normally used by pressing X on default controls...you'll need to do as follows. Keep in mind that D = X.
Forward + DD
Down + DD
Back + DD
Jump + DD
Jump + Down DD
For the jumping swords, make sure you do them close to the ground or else they won't connect. In order to set yourself up for the Down + DD swords you'll want to do a half circle away from you (moving the left stick from the right to down and from down to left all in one motion from the left side) and press C (default controls, circle). This should ram them against the wall and bounce them up, making it easier to land the swords.
I'm not sure if landing them is necessary but I did it just to make sure since some descriptions are off.
