Gladiator Begins

 is a fighting game developed by GOSHOW and published by Acquire/Aksys Games/Zen United on January 14, 2010 in Japan, on September 15, 2010 in North America and in Europe on May 27, 2011 for the Sony PSP. The game featured many DLCs, each containing a new character, costume, item or weapon, but with the shut down of the PSP frontend online shop they can no longer be obtained on the original console. The DLCs appears to have been delisted from most of the Stores except for the North American one. The PS Vita release of the PSP version allows to download all of the content, but to be able to get everything on the original hardware a Sony PS3 is needed (see below for details). Unlike games, DLCs on Playstation 3 are region locked, meaning that NA content is not compatible with the PAL game.

How to obtain
The DLCs can still be obtained on the PS Vita release from the Playstation Store or, on the PSP, by purchasing the content on a Playstation 3 system and then transferring it on the handheld console.
