So I was wrong.. The Collector's Edition wasn't the only edition for God of War: Ascension. There is yet another God of War: Ascension Special Edition revealed for the game.
This edition is a "smaller edition" compared to the CE, and comes without the Kratos Statue. Everything else remains the same including the pre-order bonus which includes the Mythological Heroes Multiplayer Pack. However, JB Hi-fi stores in Australia comes with yet another pre-order bonus, a God of War Kratos Sackbox figurine.
Pretty cool bonus for the Australian gamers who have so long been on the losing end for mature, violence-themed games. I have only seen the Kratos Sackbox figurine as a bonus in JB Hi-fi, not sure if these will be available anywhere else. Will update this post if I do.
