Yay other people noticed, i was gona post on this too, it might not be free thought like 5 bucks sounds fair, because when a game gets very popular (like halo) the companies might start making you pay (i heard from russel that they are selling map packs for like 20 bucks and some added weapons....not worth it). Survival mode could be a very intresting idea if they didnt fuck it up by making it a campaign with no medkits, thats horrible, but if it was like barricade the house, that would be awesome. Also, the sdk im exited about because i have already seen some of the maps ppl making on youtube (like the mall from dawn of the dead or w/e movie), and they will be done as soon as the sdk thing comes out
