According to the Ubisoft website, Rainbow Six Mobile is the ultimate tactical shooter game, designed exclusively for mobile that allows players to:

• Compete in Rainbow Six’s classic Attack vs. Defense game modes.
• Play as an Attacker or Defender in fast-paced 5v5 matches and face intense close-quarter combat while making timely tactical decisions.
• Collaborate as a team to set-up strategies and take full advantage of the destructible environments.
• Choose from a roster of highly trained Operators, each with their own unique abilities and gadgets.

Ubisoft also listed down what players can expect in the closed beta. They added the first stage of the Operator Unlock and Progression system. There will be daily challenges, a ticket system to play and unlock operators, and a battle pass. There are also new graphical and gameplay improvements, social features like persistent teams, and a more streamlined menu flow.

Three iconic Rainbow Six maps are part of the closed beta: Bank, Border, and Clubhouse.

• Bank: Located in the middle of a highly populated city, this heavily fortified bank will not be easy to infiltrate. Attackers will have difficulty to find the objective as the building is composed of several small and medium-sized rooms that can be easily reinforced by the Defenders.
• Border: In this map, you’ll feel isolated in this deadly outpost set at the border of two countries. Completely surrounded by deserted mountains, this map is composed of old and new buildings and is filled with open areas. Moving around will be dangerous and must be calculated carefully as it is one of the most open and destructible maps.
• Clubhouse: Every hour is happy hour in this biker gang clubhouse, a large map designed for strategic rotation and mobility. Sprawling throughout the building’s three floors are large, open rooms and plenty of destructible walls. The exterior is similarly vast and offers several interesting entry points for Attackers.

1. Ash
2. Sledge
