The old Rainbow Six is dead, and it’s not coming back.
This is the new Rainbow Six and it’s all about room clearing. The bigger picture is cast aside in favour of a linear series of rooms and set pieces, and you aren’t going to be minus Ding Chavez because he took a chest-full of buckshot in the last mission. It’s still a tactical shooter, in the sense that you can hide behind cover and sometimes the rooms have more than one entrance, but there’s no more shouting go codes and simultaneous room breaches on opposite sides of the map.
Co-op is fucking awesome though.
In summary: this is not your granddad’s Rainbow Six.
