We've scheduled the release for the open beta on the 12th of June. We advise you to sign up to Raid-Gaming.net to know when exactly the server is going up as ModDB doesn't allow us to instantly publish articles (we will however submit an article for review as soon as the server goes live). The actual time of the day at which the server will be going up will be dependant on if we encounter any issues with setting up the server.
Current State of the Mod
Currently we only have a selection of 2 maps. We are counting on the community to further develop maps for the mod. Instructions of how to create a map along with the release of the developer package (including a stripped-down version of the mod and a stripped-down server patch) will be released some time next week, most likely. The mod itself currently lacks some VIP features but that's about it. The exact features and content of the mod will be listed on release day.
