Yes, you read it right. I didn’t know that you can buy an adapter to plug a keyboard and a mouse to your Xbox 360.
How people can play first person shooter (yes, that includes HALO 3) with the controller, amazes me, really. I’m not sure if this adapter really works/helps, but it is definitely a great invention!
It’s not officialy comes from Microsoft and I don’t have an Xbox 360 to try it out.
So, if you really want to buy and try it, try at your own risk!
Some people in the Amazon reviews have it working and some don’t. I suspect it also depends on the type of mouse/keyboard.
