Great arcade styled shooter.
Graphics:
The graphics here are nothing special. There is not a lot of detail, but in a game like this it could possible slow it down. The graphics aren't bad however. There are some nicely varied level designs, but there could have been more. Maybe in downloadable content in the future. The characters are nothing realistic, but each have their own unique personality and look to them.
Sound:
I have read complaints about the gun sounds. No they are not gigantic sounding, but I think they aren't as bad as some people make them out to be. It does sound a little weak, but it gets the job done. At least the announcer never gets overly annoying either.
Gameplay:
Well in this type of game, this is pretty much all that matters. It is a mix of racing, and a combo system like in a DMC type game or something. There are 5 modes of gameplay. Siege and Survivor are basically the same thing. You stay in a confined area and try to survive while taking out enemies. Run the Gauntlet and Sprint are virtually the same except in Run the Gauntlet you have a time limit to get to the end of the level. Time Attack is my personal favorite. You do "laps" while killing enemies and collecting time clocks. Now how do you accumulate a lot of points? Combos. You simply run as fast as you can from one enemy to the next before your combo meter runs out. When it goes down your combo will start over. This forces you to keep going and not stop to look for cover. I have read complaints about no cover system, and I just laughed. This is pure run and gun people.
Replayability:
This is the main reason I bought instead of rent. If you are an old school kind of gamer you know how addicting it can be to beat your high score. This game is exactly that. Perfect your runs to beat your high score or if you have ungodly amounts of time to burn, try to get to the top of the online leaderboards. Some good competition on there. This pretty much makes the game have endless replay value if you are into the high score thing. Like I said before if you need silly symbols like other games to show the world how much you "pwn" look elsewhere. This game is all about scores.
Conclusion:
If you aren't into getting high scores or run and gun games, I would recommend to stay away from this game as there are already enough people criticizing how repetitive this game is. If you are into adrenaline rushing action, by all means give this game a shot and I think you will be surprised. Definitely a sleeper hit this year.
