Year 4 Season 1 update for Rainbow Six Siege launched today across all platforms. Burnt Horizon features a number of new additions starting with new Australian Operators Gridlock and Mozzie. Attacking Operator Gridlock’s Trax Stingers are her special ability and they work similar to how barbed wire works but does damage to any enemy who crosses them. Defending Operator Mozzie has an ability that launches bots that latch onto enemy drones allowing him to take control of them.
Various other gameplay and balancing changes were also made. You can find all the changes here.
