Ubisoft has uncovered its latest teaser for "Mission Outbreak" – the new limited-time zombie mode on its way to Tom Clancy's Rainbow Six Siege. Following a series of teasers for the month-long cooperative event, this latest trailer further establishes the mode's premise, while touching on its surrounding storyline.

Composed entirely of pre-rendered cinematics, the trailer provides a glimpse of combat among SWAT soldiers outside of the in-game Operators. Focusing on the terror of the zombie-style parasite, the trailer shares a first look at their silhouettes and how combat may play out.

The second half of the trailer follows Ash, an existing Operator from the base game, on a call with the deputy director of the Rainbow Counter-terrorism unit, "Six." Requesting backup from Thermite, Doc, and an unnamed Russian Operator, the scene lays the foundation for a more prevalent narrative throughout Outbreak. Without a single-player story mode, (or much of a narrative throughout the game at all,) this should be a welcome aspect for invested fans.

Rainbow Six Siege's Outbreak event makes its debut on March 6, before concluding four-weeks later April 3.
