Plenty of action and loads of blood and destruction!
The various mythological beasts in the game are all wll designed and look amazing, both technically and artistically. The other impressive thing is how much Greek mythology is in the game and how accurate it is. This allows for a very compelling story, which justifies the high levels of violence and bloodshed in the game (not that it really needed to be though).
Although the game is pretty short, the replay value keeps it going. This is where it seems to outshine the first game. Although the first game also had a load of extras similar to this one, here they seem to be more fun. In the first game I found myself giving up on the "Challenge of the Gods" after just one try, but the "Challenge of the Titans" in this one is a lot more fun. Therefore I was happy to pour hours into trying to do all of the ridiculously hard challenges!
Of course the main appeal of the game, like the first one, is fun. Regardless of the extras it's the enjoyment of going through th game that'll keep you playing. Even after the PS£ has come out this title proves that there's still life in the good old PS2 yet.
