Well, I just finished Dark Sector and I really enjoyed the game. I was not very impressed with the multi player and just thought the game should have focused on single player more because I lost interest in the game once I finished and tried multi player. The single player story is not very deep but thats ok because throwing the glaive is what its all about.
I couldnt get enough of using the glaive and just stuck with it for most of the game. There were a few hard situations where I had to pull out a 9mm and put a cap in someones ###( you get the point). But beyond the small need for fire arms the glaive pretty much did the job and was a ton of fun to throw. I would like to see Dark Sector expanded upon with another single player campaign. I think this style of play has a lot of potential and is currently unique. This untapped potential could mean a lot of cash to developers but due to the "pray and spray" nature of first person shooters this game needs to be configured for the type of play like a tactical shooter such as any rainbow six game not like halo.
Lots of fun and definately received my dollars worth out of this game.
Have fun!
