Rainbow Six: Siege

Ubisoft's revival of Rainbow Six launched quietly late last year, but its tail end seems to be growing the longer it stays on the market, becoming a huge hit in the process.

Ubisoft has launched the open beta test for Tom Clancy's Rainbow Six Siege following a last-minute delay.

Rainbow Six Siege was supposed to enter open beta today. However, Ubisoft has decided to delay the test indefinitely.
