Awesome game. My review:
Cons.
Too short, i wan't more. Finished it in one day (I was sick.)
Lack of multiplayer, but then again, how could you play that in multiplayer??
This one was my biggest: Lack of stealth possibility in some areas. I love games where stealth is needed. The Chronicles of Riddick: Escape from Butcher Bay, is one of the best stealth games i have played. However, there were some parts which were extremely difficult to do stealthily. You end up trying again and again and again, until you know exactly how you should do it. I hate that, because it doesn't feel very professional, and i have a thing about playing games really well. But that's probably just me. It may have been better if the "gun-ho" areas, and the "silent but deadly" areas were clearly defined. Such as the pits.
Pros.
Too many to list here.
Great, almost perfect, graphics. Superb environments, and movement.
Awesome sound, especially with surround. And Vin Diesel's voice is really cool.
Very original, with some details which are not seen in other games.
The prison levels actually feel gritty, with lots of swearing, prisoner malice, etc. Very well done atmosphere.
Interesting story line, that gives some background to the other two Riddick movies.
The constant feeling that you are in complete control of your situation, and the awesome feeling of power when you can see in the dark and no-one else can. Vin Diesel, the hunter. Stupid guard: the defenceless prey.
