Those of you that have been involved in the God of War: Ascension social game via GoW will be able to access the single player demo very soon if you were on the winning team. Choose Warriors or Spartans, once you’re involved you’re in the fight; the first team to hit 10-million points will earn early access on the 20th with the rest having to wait until the 26th. Most importantly, everyone who takes part will earn exclusive multiplayer DLC costumes and weapons (seen below).
