As a city drastically changes from the release of a deadly, mutating virus, a shape-shifter known as Alex Mercer, is changing right along with it, gaining powers as he consumes more and different types of the virus. Unfortunately he has no memory of what happened and must gain memory of the incident back through absorbing enemies and military units. This absorption power is also how he gains some intense shape-shifting powers and he grows stronger as he gains experience and absorbs the right people. Stealing powers and defeating enemies unlocks new abilities purchased through experience points or gained directly from the enemies. These powers gained allow Alex to shape his body into new weapons used to defeat enemies as well as learn how to take over enemy vehicles such as tanks and helicopters. The action in this game is always intense so there is never a dull moment from start to finish. Check out the top ten reasons that you need to get this game if you haven't already.
