Ubisoft has revealed the full details for Rainbow Six: Siege's upcoming Operation Grim Sky update, and it's clear that this is as much about changing the mechanics of the game itself as it is adding some variety. Both new characters, Clash (above) and Maverick, will introduce gadgets that should force experienced players to rethink their strategies. Clash is the first defender with a shield, and hers includes a built-in taser -- she can slow down and damage anyone who gets relatively close. The attack character Maverick, meanwhile, can use a blowtorch to quietly cut holes in just about anything to take out unsuspecting enemies and disable gadgets. You can't assume that a wall is safe simply because you didn't hear anything.
