Ubisoft have revealed new details on their upcoming  Tom Clancy’s Rainbow Six Siege, giving prospective players a better idea of what to expect.

The studio has put out a new behind-the-scenes video showcasing the Rainbow operators that players can choose from. Given that the premise behind the Rainbow Six series revolves around a team of elite special forces operators from around the world, it makes sense for Siege to feature this in some capacity.

In each of the game’s five-on-five multiplayer matches, players will have to choose from a pool of 20 operators, each with their own traits and kit. “Each operator has their own unique ability, which expands the potential for teamplay,” explains Creative Director Xavier Marquis, “We’re following the original storyline.”

Game Designer Andrew Witts adds:

What the operator system does is it gives a lot more ingredients for players to interact with. If you like being a breacher and you like destroying stuff, you can select an operator who best suits your abilities and compliments everyone else in the team structure that you have.

Each of the 20 operators will be drawn from five of the world’s best special forces units: the GSG 9, GIGN, Spetznaz, Special Air Service, and SWAT.

Meanwhile, PC Gamer have uploaded their own hands-on video of the game, which shows how multiplayer matches in Siege begin with one team setting up defenses and the other team sending in drones to reconnoiter the area, and then end with one team massacring the other. There’s a heavy emphasis on making the best use of each operator’s special abilities and tools, and less focus on twitch-based shooting in similarly themed shooters like CounterStrike.

Each map’s environments are also largely destructible, which opens up a whole new level of unpredictability. For instance, a player with a heartbeat sensor, which can see enemy heartbeats through walls, can direct his comrades to focus their fire on a specific wall.

In spite of all this, there’s still no word on Siege‘s single player mode. Ubisoft have not revealed anything about this crucial element of any Rainbow Six experience, and with the game due for release sometime this year, all signs are pointing to a Call of Duty styled token single player campaign. We’re hoping Ubisoft will prove us wrong.
