Rainbow Six Extraction’s first post-launch Crisis Event, Spillover, is available now. We go hands-on and learn that there's no amount of claymores you can lay down before you feel 100% safe and sound.

Spillover is also the game's version of a straight-up 'horde mode'.

The stealth component of Extraction is set aside as you fend off alien hordes whilst trying to neutralise Sprawl Colonies. The tactical side of Extraction remains in full as careful Operator selection (defensive and support) will be one of the things that results in success over failure. The arrival of new-to-Extraction Zofia also ties in nicely to the Event as her grenade launcher is a surefire way to thin Archaean numbers. Which also works a treat when paired up with a Tachanka mounted turret.

How the Crisis Event works is fairly similar to that of a traditional ‘horde mode’, albeit with a 25-minute timer always counting down. Setup and defence is key, choosing the right Sprawl Colonies to target, making sure you’ve got the right gear equipped (drones are essentially useless here), and knowing that as soon as you place a bomb on a Sprawl Colony it’ll trigger the arrival of the horde. The goal is to try and stop all 9 Sprawl Colonies on a map, within the time-limit, whilst legging it to the extraction zone in one piece.
