Ubisoft have been angels with their downloadable content releases since Rainbow Six Siege launched at the end of last year and the latest addition Operation Skull Rain offers the most colourful free map of them all. Gamers can now partake in some close quarters combat with an Olympic flavour with the Favelas map which comes in two guises, day and night. It’s a pretty tough map when playing Terrorist Hunt mode solo but keeps the tension high despite the colour rich backdrop of painted walls and the iconic Rio statue of Christ the Redeemer in the background. Take a look at our gameplay video of Operation Skull Rain Favelas map in 4K and drool – although it has to be said our GTX 1080 FE struggled a little here compared to the other maps.
