This game was a solid upgrade to the first. It is like they sat down and asked " what was wrong with the first game and what can we do better"? For many things, they delivered on this well: Better upgradable abilities including several new forms of the regular bolt , improved melee design ( they actually have combos now), better side quests, and even the nice little option to make your own user generated side quests. There still are some issues from the original game like how slowly you scale buildings and the way that you sometimes cling to things when you intended to jump over them, etc. They added a few treats mid way through and towards the end however that greatly alleviate these issues. Only shame with that is these abilities should have been available sooner. This sequel brings to a close already the story of Cole. The story ended well and my only complaint is that the series is over. Some reviews talk about how bland and uninvolved the characters are, I have to say that I really do not agree with this entirely. Sure, there was some room for improving on some of the character personality design but they were believable and engaging enough to feel like they fit there roles. All in all this game is worth the rent or even the buy if you are a fan of the franchise. It's a solid improvement over the first with plenty of replayability.
I sorry fanboys but I can't stand by this game . They didn't fix any of the bugs or glitches from the last game . You be doing a combo and then out of the blue go through a building . Some Blast shards may show up on the map but once you go the location they are not there and so have leave and come back later for that part of the map to reload . Or they are there and you just can't pick them up.
They really didn't change anything they just added some more powers and new characters . It feel like you just playing some DLC for the first due to the fact that all the bugs and glitches from the first one is still in the game. If you enjoy the first game feel free to play it for yourself this is only my opinion.
