Some people have already played the new map(due to friends that work directly in development of the project) as beta testers. The game was completely grey except the guns and characters(zombies and player's arms) Sound was disabled and my job was to test the barriers and find glitches for my friend. I can't give out any details(probably because he would find and kill me) but it is an amazing map and I can guarantee that it will be a lot of people's new favorite map. There are some new surprises to look out for and I believe that the zombies are harder than before(but they fixed that one problem where zombies smack you once and it acts like two hits. Since this was a controlled environment that game didn't go past a certain point. There were a lot of glitches at that point so I'm not sure how far along the level was. Since this was about a month ago I think it may be one of future ones but I'm hoping for it to be Ascension. I want to see what this map looks like with textures enabled because it was even better than any of the zombie maps that I have seen so far. You can choose whether to believe me or not but I met this person at college when we were both taking game design courses, unfortunately he's working on one of the greatest games ever and I'm unemployed because of certain reasons...
EDIT: He was always the best in the class and seemed to soak up knowledge instantly so obviously he would become something amazing in the future, even if he isn't one of the head developers. But since I was better at finding bugs and glitches he came to me... Before asking which system you should know it is easier to use a computer to play the game so you can monitor the script and fix error codes that pop up. Of course he did all of the editing, I was only allowed to play with him standing over my shoulder.
Now it's only 15 more days(I don't have an Xbox so I don't know how long it will be for me but luckily another friend of mine is going to come over and play it on my big screen as we drink So-Co and Java Monsters which is surprisingly good if you don't die from alcohol poisoning).
