So I finally finish FSN Fate, Unlimited Blade Works, and Heaven Feels. If you have Realta Nua install in the Last Episode will be made available after getting all of your Tiger Stamps. Realta Nua aka PS2 version of the visual novel game. It adds some new CG and Last Episode. The Realta Nua patch can be found here.
This is follow up on the Fate route after Shirou dies he is able to meet Saber in heavenly field of Avalon. As Shirou has been searching all his life and Saber has been wait forever for Shirou. A happy reunite! Saber still the best after all. BTW after I install the patch, last episode was made available when I don’t even have all the Tiger Stamps.
