Prototype is an entirely different type of sandbox game that will attract and please most gamers. There are plenty of objects to collect, a wide variety of abilities to master, and the story is very engrossing. But, like most open-ended games, it suffers from its share of downfalls. They're mostly typical of the genre, however, including downgraded graphics, lack of interactive environment, and hit or miss voice acting. Overall, however, Prototype creates an interesting character in Alex Mercer and hopefully is a sign of things to come in future games.
