Dynasty Warriors: Strikeforce

Dynasty Warriors: Strikeforce is an hack and slash game developed by Omega Force and published by Koei in 2009 for the Sony PSP and in February, 2010 for the Microsoft Xbox 360. The game featured 8 DLC packs, but not all of them are still available. With the shut down of the PSP frontend online shop they can no longer be obtained on the original console. The PS Vita release of the PSP version allows to download part of the content, but to be able to get everything on the original hardware a Sony PS3 is needed (see below for details). The browser version of the European Store does not list the DLCs, but Packs from 5 to 8 can be purchased from the European PS Vita Store and 1 to 8 from the North American One. The Xbox Live service does not list them or the game. The Playstation 3 version Packs are all available.

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