We have a date in mind for release; July 15th! We are working hard on testing and finishing the very last details of the mod in preparation for release. There is also a new article on PCGamingWiki which will list solutions to any possible errors you may have. To prepare for release, make sure you own Portal 2 on Steam (Else, steam won't let you buy Aperture Tag). Then make sure you have Portal 2 installed. If you have some mods installed, it's possible they may break certain aspects of Aperture Tag, so I also recommend doing a 'verify integrity' check on Portal 2. The strings for the game have been out for translation since Wednesday! if you want to help translate, be sure to head over to the Steam Translation Server and help out there! I will be adding the new translations as they arrive and also update the store page to let you guys know which languages have been added to the game. http://translation.steampowered.com/ About Coop. Coop is hard to make. Specifically, without access to any of the source code and when everything is done via hammer. Heck even less than hammer as the level editor has to preload instances which makes matters extra difficult. The current state of Coop is that it's playable, and its fun, but it is not as polished as I would have wanted to. There is bug which makes it so that sometimes your paint gun works and other times it wont work properly, and it seems to be compeltely random, so when playing Workshop Coop maps, you may need to click multiple times until you get your gel. I will keep on trying to solve this issue, but rest assured, the coop area of the game is still playable. And remember we are all on the same boat! I also can't wait for release! I am off back now to work! Thanks for the support! -Motanum
