A while ago I bought God of War: Chains of Olympus, and it blew my mind. I had never before realised the capabilities of the PSP, and everything about it was fantastic, from the graphics to the gameplay. The only slight chinks in the armour were the story, which I felt a bit too disjointed, and the boss battles, of which there were few and only one was on a grand scale.
Therefore I had extremely high expectations for Ghost of Sparta, and they were both fulfilled and exceeded.
The graphics have some how been stepped up a further notch, with Kratos being completely re-modelled and with many fantastic-looking new enemies. The scenery is breathtaking from the very first fight all the way to the final battle.
Gameplay has also been improved, with more variation in how to move around, with grapples from the original god of war series being introduced as well as sliding down slopes and edging through cracks. In particular the temple of Thanatos is like a giant obstacle course full of fun, sweeping movements. The fights are the same tried and tested formula which GoW fans will love and beginners will easily get used to, and the new weapon has plenty of depth and is a lot of fun to use.
Boss battles are another huge improvement, with many mini ones thrown in to make the game more challenging. The main fights often consist of multiple parts and it is fun trying to work out the best strategy to get past their attacks and strike the killing blow. Watch out for the fight with Erinys, for this must be one of the best boss battles I have ever played on the PSP.
The story is also more logical and flowing, as you move gradually from area to area, rather than seeing a cutscene and ending up somewhere completely different, as is what happened in Chains of Olympus. The actions of Kratos all make sense, and if you have played God of War 1-3 it gives you a great background on his endless rage.
All in all, if you have a PSP, buy this game. It may sound like I am merely trying to promote it, but I enjoy writing critical reviews and I honestly couldn't find anyhting wrong with this game other than the fact that I eventually have to turn off my PSP and go do work.
