I'm prying the winners list from the design team as we speak. Sorry it's taken so long, but hopefully we'll be sending out prizing soon. Once the prizing is out the door we'll post the winners up on the site. As for the winning maps, the designers of those maps will receive prizing but there won't be any official release of them.
Nope. There are no plans for any new prestige ranks.
Nope. There are no plans for any new guns or ranks to be added.
As soon as they're finished translated and through QA. We found some bugs in a few of them, so we're working on fixes and / or additional playlists to try out.
At this time we have no plans for any additional map packs.
We're hoping to get new playlists into the game, but other than that we have to start looking forward to future projects. We love making map packs and DLC for our games as long as possible, but eventually we have to start working on future projects so we can continue to raise the bar, project to project.
