You might remember that Fate/zero is a prequel to the earlier Fate/stay night, but remember how Cavia's Fate/unlimited codes was released back in 2009? The bad news is that publisher Capcom decided not to the renew the license, but the good news is that there's a goodbye sale.
Between now and when it expires on June 12th, the PSP game can be purchased on PlayStation Network for $9.99.
