Kratos' brother Deimos will soon be playable in God of War III.
But Sony's announced that the only way to unlock him will be to use a code supplied with God of War: Ghost of Sparta on PSP.
Deimos will be a skin for the existing Kratos character model. However, Deimos is rather powerful, and has enhanced combat damage and four times the health, magic and gold orbs.
When will Ghost of Sparta be released in Europe? Sony's "targeting" November at the moment, a spokesperson told Eurogamer. It'll definitely be out this year.
There's a new video of Ghost of Sparta to go with the news on the European PlayStation blog.
