Those who are looking forward to Tom Clancy's "Rainbow Six: Siege" will have to wait a little bit more as the game's beta is locked for most users. Fortunately, Ubisoft has designed a fun and easy way for players to access the closed beta.

According to Game Spot, the developer launched an interactive website called the "Rainbow Six: Siege's Art of Siege," which allows users to learn and master attacking and defending the game's maps. The field training exercises get players more prepared for the hotly anticipated game. Upon completion of training, players will be awarded access to the beta.

The closed beta for PC, Xbox One and PlayStation 4 will be launched on Sept. 24. Those who pre-order the game will be able to access this beta even without undergoing "Art of Siege."

The "Rainbow Six: Siege" is slated to be released on Dec. 1. It was originally set for an earlier release date, but the developers decided to postpone its launch to make necessary adjustments to the game.

"Based on the feedback we've received, and based on our own internal tests, we felt there are adjustments and improvements we can make," Ubisoft announced in an official statement on their blog. "Including improving the co-op experience across all game modes, weapon and gadget balancing, as well as menu and interface navigation. We're taking a little more time to make these changes, and we think it's the right call."

Although the announcement was met with some disappointment, the hype is ongoing for the upcoming shooter video game. It's expected to be one of the top-performing game in Ubisoft's roster, even ahead of its release date.

In a report from Game Spot last May, Ubisoft CEO Yves Guillemot confirmed that the company has a positive outlook for "Rainbow Six: Siege".

"Over its lifetime, we believe 'Rainbow Six: Siege' has the potential to become the highest-selling shooter in Ubisoft's history," he said in a conference call with investors. Later he also said, "It's very important to consider that this game will continue to live for a long time as we will introduce new content on a regular basis because it will be a multiplayer game."

Ubisoft's CFO Alain Martinez added, "We believe that Rainbow Six - because of replayability and multiplayer - might have a potential to [do] better than Far Cry over its lifetime."

The Gamescom trailer of "Rainbow Six: Siege" captured the thrill and excitement of the shooter game.
