Rainbow Six Siege's Alien Outbreak Mode Is Completely Different To Traditional Siege

Rainbow Six Siege has changed significantly in the two-and-a-bit years since launch. The Operator number and map count have nearly doubled, strategies have evolved, and we no longer all sit in one room, terrified, waiting to be picked off by attackers. But we are essentially still shooting similar guns at similar enemies, just in different combinations. Operation Chimera's Outbreak event, however, is the first PvE update Siege has received since launch, and it is markedly different to anything the game has seen before.

Starting March 6, it's a one-month co-op event that sees you and two companions team up to fight an alien invasion in the New Mexico town of Truth or Consequences. Three missions are included--colloquially known as Junkyard, Hospital, and Resort--and you can pick from new Operators Lion and Finka as well as veterans Smoke, Ash, Doc, Glaz, Kapkan, Tachanka, Buck, Ying, and Recruit.Outbreak feels distinct from traditional Siege gameplay, eschewing the usual attack/defend dynamic in favor of more explorative scenarios. In Hospital, for example, you must escort Doctor Macintosh around the veterans' wing of her hospital while simultaneously collecting samples, defending jammed doors, and escaping the building alive. Junkyard and Resort, on the other hand, see you safeguarding explosives as you attempt to destroy the visible signs--columns of miscellaneous alien matter--of the zombies' infestation.

This is as close to traditional Siege as Outbreak gets: you still barricade doors and reinforce walls--albeit with much faster animations to account for the increased number of enemies--and can lay Kapkan traps and claymores. It's here that Outbreak feels much like earlier Call of Duty games' Nazi Zombies maps. However these periods are brief: you usually only need to defend that position for a minute or two before moving on to the next objective.
