Easily one of the best PS3 exclusives to date
This game lets you play as Cole MacGrath, a courier in Empire City who inadvertently sets off a bomb, destroying half of Empire City and causing a plague that turns the entire city into a giant quarantine zone. The story then takes you on a path of vengeance and justice.
This game introduces a new twist in how the story goes, allowing you to be the hero or the villain based on a karma system. There will be points in the game that question Cole's moral values, such as whether or not you let civilians take some government food, or taking it all for you and your friends.
There are other moral dealings in the game that allow you to gain more good or evil karma throughout the game. The karma system that I mentioned earlier allows you to become good or evil depending on what actions you take during the game. For example, if you stop to heal a citizen, that gives you good karma. But if you drain that person's energy for your own, that gives you evil karma. This same system also gives you a choice of what powers you can use later on in the game. It also changes the story somewhat, even though the initial story remains largely unchanged.
The combat system in inFamous is seamless in every way. It gives you an over-the-shoulder combat screen similar to the one used in Resident Evil 4, but the one in this game uses highly destructive electrical based powers that can be upgraded with the use of experience points. The fighting is very easy to get used to, and the only mistakes that happen with the fighting are the ones that you make on occasion. The enemy AI is surprisingly intelligent, however, so you'll have to move around to try and stop some of the runners and shooters. The upgradable powers become very handy once they've reached full power, but they vary with your current karma level, such as lightning bolts that refresh your health when you're good, or shock grenades that cluster into multiple mini-bombs when you're evil. Either way, combat's fun and easy to handle when you're surrounded by many enemies.
The environment is a large, three-island city that has many buildings and structures that Cole can easily latch onto and climb effortlessly. The travel system in inFamous is based on scaling buildings with incredible ease and finesse, much like Asassin's Creed II if Ezio had a few Red Bulls. Cole, being an urban explorer, can grab on to any surface as long as it's climbable, which helps out greatly when you don't want to fall off of a building from a large height (not that it matters anyways, considering that Cole can land without injury from such heights.) The only annoyance with the climbing is the fact that Cole grabs onto anything very greedily and thus makes landing accurately somewhat difficult. However, this annoyance can easily be overlooked after a few hours of playing.
The only problems that arose when playing were mainly graphical. There were a few instances of running through objects and having a "see-through" Cole when you zoom in too closely. Plus, the city has a few sharp edges and somewhat undetailed buildings in it. But in any case, these problems aren't much of a hassle when compared to the excellence of gameplay and the gripping storyline that comes along with inFamous.
