Unlock Guardian Force Leviathan
How to unlock Leviathan
Once the Garden is mobile, Squall and co will be forced into a battle against NORG, one of the founders of Garden. During the battle you can draw Leviathan from him. The trophy will pop once Leviathan is drawn.
Alternatively, if you missed Leviathan the first time, it can be acquired in Ultimecia’s castle by drawing from the Trauma boss.
