Apparently DICE is saying if players do 69 million team actions when the new 'Nam DLC comes out, they will release a 5th map for FREE. On one hand it's sort of a neat idea. But on the other it's like, come on guys you already have the map done. Just release it with the DLC for christ sake.
Don't try to trick us again by with-holding content then offering it up to us later for FREE so we will think you're so great and charitable. That's a shitty thing to do. DICE I am disappoint.
The DLC still looks good though.
