— In-game description
The Super 90, or the M1S 90 on the PC version of the game, is a weapon featured in Tom Clancy's Rainbow Six: Lockdown.
In the console versions of the game, the Super 90 is equipped with a Red Dot attachment by default.
In the PC version of the game, the M1S 90 does not have the Red Dot automatically attached like in the console versions of the game. The M1S 90 is used by the New Freedom Army in the mission Amsterdam, by the United Fatherland Brigade in the missions Catacombs, Distillery and Hospital, and by the Marxist Radical Front in the missions Docks and Cruise Ship. The M1S 90 is the standard weapon of Ayana Yacoby.
