English Title: Guilty Gear XX Λ Core PlusThe very last Guilty Gear title released on the PS2, Λ Core Plus is a revision of a revision of a sequel of a sequel (yo dawg). Tons of balance and bug fixes, a new story mode, the curious "Generations" mode from Λ Core, the return of Kliff and Justice (again). This is the difinitive Guilty Gear experience on the PS2.

There's actually two different versions of this, this standard release and an "Append" version that requires the original Λ Core to boot. The latter was released at a *heavily* discounted price as Arcsys' apology to anyone who bought the original version. I wasn't kidding when I said it was a mess.
