For them being free, it's a great expansion...I was bummed you couldn't fully level a building like in BC2 but it was definitely an improvement from the original maps. I even tank shelled a random building and the debris fell and killed an enemy player who ran under it as he spawned.

I didn't get the DESTRUCTION 2.0 message that was fun seeing in BC2 but ah well.
And if you're wondering, the first thing I did was pick C4 and go look for a building that could possibly crash down. Blew up every wall only to see the building standing with a damn staircase.

They're good maps though, Wake Island is the only one I have trouble with because I seem to get the No gun spawning glitch when I get out of a vehicle. Plus the color scheme isn't as bright as 1943s so it's eh..
