There is something I like to do on this map is shooting all the lights in the corridor underground between C and D and so you can't even see a shit without a lamp or a flare. And then you can put Riz's claymores everywhere and it's a big explosive mess in the dark.
(And it's better in hardcore...with friendly fire of course) And so you read the kills history and you see that you killed 2 teammates. "Oops" ; "Who the fuck turned off the light?"
Looks at a tin of cocktail sticks. Mmmmm stabbing them in my eye sounds fun.

Been playing a few times recently on Metro and Locker where the main battle was around B and C flags and it was actually quite fun. On Metro when you are just stuck in base there is no easy way out but on Locker you have quite a few options and routes to turn things around.
