Developer Ubisoft announced that it has resumed the open beta event for the upcoming "Tom Clancy's Rainbow Six Siege."

The announcement came a day after the development studio postponed the public test event due to various server-related issues, Gamespot reported.

Originally, the open beta for the tactical first-person shooter was supposed to commence on November 25. However, the developer decided to stop the beta event after experiencing several issues for the PlayStation 4, Xbox One and PC versions of the game.

As detailed by Ubisoft, some of these problems include matchmaking times and constant disconnection. These then led the developer to change the status of the event to a closed beta.

"We're currently seeing issues with matchmaking times and disconnection on all platforms," Ubisoft stated in its forum page. "As such we're postponing the Open Beta until a later time and keeping the game under Closed Beta status."

"We apologize for the delay and can assure you this is our top priority," the studio added. "We will keep everyone updated regularly as we continue to deploy improvements."

Fortunately, Ubisoft was able to resolve the issues affecting the beta event for the game. November 26, the studio announced that it is ready to host the open beta event for the gamers.

"We are happy to confirm we will be launching 'Rainbow Six Siege' open beta at 12pm EST," the company said in an updated post. "We want to thank everyone who is participating in this beta. Your feedback helps us improve."

Of course, since it is only a beta event, gamers will not be able to see all of the features of the game. But still, it comes with various playable contents including three maps, three game modes and 14 operators to choose from.

The official and final version of "Rainbow Six Siege" is expected to debut on December 1 of this year. It will be released for the Microsoft Windows, Xbox One and PlayStation 4 platforms.

The game will allow players to take on the role of a member of the Rainbow Six special unit. Each character or operator comes with his own set of skills and items that players can utilize to complete the different missions.

Like the other titles from the "Rainbow Six" series, "Siege" requires strategic planning and perfect execution from gamers.

"Siege" does not have a traditional campaign but it will feature a sing-player tutorial mode dubbed as Situations.
