Sigrun – God of War

God of War‘s base campaign might not be the most grueling of a challenge for most gamers, but those wanting to see all that the game has to offer should definitely be ready for some pain. To even face the queen of Valkyries Sigrun, players will first have to hunt down eight Valkyries all of which are some of the hardest end-game challenges in their own right. Of course, Sigrun being the queen is the most powerful of the bunch – and to even stand a chance of defeating her, players will have to collect the best gear and power-ups possible before entering the arena.
