Tom Clancy's Rainbow Six Siege: Deluxe Edition

Rainbow Six Siege's focus on teamwork and strategy over just aiming prowess sets it apart in exciting ways, and the constant stream of new maps and operators have made it a wonderfully varied FPS. All that new content has made it harder for new players to catch up, and I wish more work had been done to address this, but smart play and good communication will still win you more games than having the newest operator. It's got some growing pains to sort out, but the future continues to look bright for Siege.

More than four years after the game's release, Rainbow Six Siege has evolved into not only a compelling shooter but one of the best examples of the genre.

A joyous, deep and rewarding tactical shooter.

Rainbow Six Siege is a pretty dopey military FPS at first glance, but insists players learn to work together with minimal error. Further, it invites a maddening cycle of thought—it makes me think about how I'm thinking the more I play. We were constantly disrupting our own habits.

Rainbow Six Siege is already fighting a difficult battle trying to enforce a more methodical vision of a competitive shooter. It's a minor miracle that Ubisoft Montreal has built such a solid foundation in that regard. But the bizarre progression hooks Siege borrows from free-to-play games, its dearth of content and its network problems make for an awful lot of frustration to overcome in search of those rare moments of unit cohesion.

Rainbow Six Siege now finds itself in the best position it's ever been in for player onboarding.

The lone multiplayer mode has great promise, but technical shortcomings need to be ironed out. Single-player fans will be disheartened by the lack of meaningful options

With its taut, tense action and destructible environments, Siege is the best Rainbow Six for years – if only Ubisoft would rethink its business model

Games like "Siege" flatter these desires by letting them play out in simulation, endlessly repeating on the screen. Stripped of the vanities of many other shooting games "Siege" is both unforgivably callow and inarguably satisfying. Like parades or fireworks, it's a vision that's only fun if you can forget where it comes from and where it points to.

For all of the wonderful craft on show, Siege doesn't contain any surprises. It executes its plan to perfection but there's no room for deviation.
