Publisher 1337 Games announces closed beta testing for Tactical Intervention begins today, as promised, offering the unusual prospect of a closed beta for a game that's already had an open beta and has been released. According to Wikipedia, the servers for the game were brought down by OGPlanet on June 10th because "player involvement has yet to reach a level for OGPlanet to sustain its future service" (the post on the topic is no longer available), even though they gave the game almost a full two weeks (13 days to be precise) to make its mark. They say the game will re-launch on September 12th as a free-to-play title on Steam, and offer a new trailer showing off gameplay and reminding us of the Counter-Strike pedigree of creator Minh "Gooseman" Le. Here's word on how those interested can get access to the beta:

Berlin, 22nd August 2013: Players who want to take a look at the new Tactical Shooter, developed by the Co-Creator of Counter Strike Minh “Gooseman” Le, even before the official release can rejoice; Tactical Intervention is playable from today at the gamescom booth of the Publisher 1337 games (Hall 8, Stood B020). In addition, lucky winners of a key for the Closed Beta phase can plunge straight into the action-packed battles between terrorists and counter-terrorists now! Everyone without a key, should take a look at the Tactical Intervention Facebook page as during gamescom, there will be plenty of keys up for grabs in raffles and giveaways!

In collaboration with the Community, Tactical Intervention will be continuously improved and expanded. By the end of the Closed Beta on the 28th August, players will have been able to test the shooter and contribute their feedback and their suggestions in pursuit of an optimal Release-Version. Interested players that had no opportunity to get a beta-key will have, from the 29th of August, their chance to get involved with Tactical Intervention in the Open Beta phase.
