This is not Chronicles of Riddick: EFBB by any means. Starbreeze fell a little to short. GREAT RENTAL!
Without giving away the plot, the game is not realistic to any extent. Most of the things that happen to Jackie early on in the game that would not be considered normal by any means, are just neglected by Jackie who seems to not care or take knowtice. Maybe its because he feels godly or something, but its rather rediculous in my oppinion. The game features some cool abilites, Jackie gets to use the powers of the darkness throughout the game. Some of things that happen when using these powers are quite gory and satisfying, but not to the extent of a game such as Gears of War. There are only about 6 guns in the game and they are not orignal and do not feel to work right (shotgun is terrible). Your character moves like a slug, and in order to use the darkness, you must turn off the lights. While playing through this game, I found I was turning off the lights more than I was acctually fighting enemies. Half of the game is spent in a world much like hell and it is rather a pain to get through, rather than acctaully enjoyable. The games AI is straight out dumb. It is really bad. You have these little darklings that fight along side you, but are more of a pain than a help. If they enter the light they die, but for some reason they do this on there own. They don't stay away from the light. Also, I had one darkling set up his machine gun pointing at a wall and firing, WHAT THE HELL!!! Visually this game is high end. The environments and the lighting is gorgeous. The only complaint I have is that most of the characters faces are off par with everything else. They do not look very nice. This game is close to the Unreal engine, but still not as good.
The sound is where this game shines the most. The music fits with the tempo of the game. When your in a fight it may start playing rock music, but then when your just strolling around in the subway its calm rather depressing music. The voice acting is well done as well, and is performed by several big actors.
The reason this game is of poor value, is that it is only about 10 hours long and is relativily easy (singleplayer). The hardest part in the game is the very beginning. The multiplayer is not even worth trying. It suffers from major lag and connection issues, terrible auto-team selection (it will make you switch teams in a match), the guns do not work very well, darklings are a dumb idea (little demons from the single player, that at are fast but do very little damage), and most of the things that make the Darkness unique and that were featured in the single player are no where to be seen in the multiplayer (Darkness powers, none). I definitly compare this games multiplayer to be similar to FEAR's but even worse.
You can definitly see that Starbreeze tried to make this game as much like Riddick as possible. The beginning of the game is much like Riddicks, where it starts off just like a movie. Unfotunaelty the great gameplay mechanics from Riddick did not transfer over at all.
If you need to get a game for the summer, just buy one that has already been released. This is a great rental, no more than that. Wait until Bioshock, that is the game to buy. Stay away from this one. This should be called PREY 2!
