I DL this last night also, it has 7 new maps and a "deleted" mission for 1200 ms points. I like the new maps, makes me want to play more Horde, haven't tried the mission yet. They also have a DL for 1600 points where you get the Dark Corners and you get all available Maps.
I have been doing horde alot lately, its pretty cool. The farther you get the badder the horde gets, last mission I did I was surrounded by 8 boomers...
Yes that mode is very addicting. Did you play over the 4th of July weekend when they made every tenth wave Tickers only, that was a blast (no pun intended.) They added new achievements also to the new stuff
Yeah it is, usually you only get about 3 maps for 800 points, but this DL gives you 7 plus a mission for 1200, and if you don't have the other 3 DL map pack you can get the whole bundle for 1600 points.
