Prepare for a Brutal Adventure
I'm not sure how to comment about the story of Prototype, but it's been used quite often in games and films. It's quite simple, but it's not too weak. Radical Entertainment was able to spice up the story with "memories". Without "memories", the story would have been a totally unoriginal, because looking back at consumed people's memories makes it more unique. As a person that doesn't really look into story a whole lot, I don't really make a big deal about stories.
The one thing that caught my eye on Prototype was the gameplay. Tearing and ripping people apart never looked so much fun. Consuming people was also a cool feature. There's so much to say about the gameplay of Prototype. I praise Radical Entertainment for gameplay, because without the awesome gameplay... this game would have been a total disaster. In Prototype, you can slice, consume, rip, and do other brutal stuff with people. It's a ton of fun, but buying this game just for that can get repetitive.
Unfortunately, I have to say that the gameplay was probably the only positive and the story was the only neutral. The graphics was a disappointment. Manhattan does not even look like Manhattan, and there are constant pop-outs all the time. You literally have to stand next to the orbs in order to actually see and collect them. Fortunately, the flashy animations and blood saved it from being a colossal failure. The developers were able to create such awesome animations, and all the blood and gore was just awesome. I have to say that these animations made the experience of ripping people apart a lot more fun.
Prototype is an action-adventure type game that should be something that you should look into. Please do not compare this to inFAMOUS, as they are both different in many ways. The missions in Prototype do not ask for a specific power-up or skill to be used, but the many power-up and abilities are just amazing. If you are okay with the graphics and some glitches, you should definitely pick up Prototype, otherwise a rent will be good too. If you actually do play this game, prepare for a brutal adventure.
