King of Fighters XIII (Xbox 360)
Just started. I've beaten the arcade mode a bunch of times and unlocked a load of basic achievements. The online for this game unfortunately isn't very good -whilst it is at least much better than the previous game, it still isn't up to scratch. I haven't really got a set team I always use online. Takuma is usually always one member, but then the other two members can be any of the following: Robert, Ryo, Terry, Andy, Yuri or Kim. I guess my best achievement so far is the win five ranked games in a row one. Oh, and despite the lag, everyone playing this seems to quite well mannered. Apart from iTz I CeReBrO I.
BlazBlue Continuum Shift (Xbox 360)
I beat arcade mode with everyone and made quite a bit of progress into the story mode with almost all characters. As with the previous game, the story mode is in-depth and each story can easily take one or two hours to complete if you find all the routes and listen to the conversations in full. Some of the joke endings were stupidly amusing, I liked Tager's the most. The only character I've yet to beat story mode with fully is Hazama.
Call of Duty Modern Warfare 3 (Xbox 360)
Same war, different day. I think I have around half the campaign beaten on normal difficulty, and me and a friend have made a very small amount of progress into the special ops mode. The thing I like the most about this so far is that you can now finally have two players playing online on one console via split screen. I'm up to rank 38 online.
