R6S Y9S1 Operation Deadly Omen All Changes

Deimos: New Attacker

R6S Y9S1 is introducing Deimos as a playable character. Deimos is a 2-speed 2-health Attacker, who brings his unique gadget called “DeathMark”. The DeathMark gadget is a small stealth helicopter that can exactly track a defender’s position, similar to the tracking when inside Grim’s gadget.

Deimos can bring the AK-74M assault rifle or the M590A1 shotgun as his primary shotgun. He also has a new secondary weapon – the .44 Vendetta revolver – that sports a one-of-a-kind magnified scope. He’ll also have frag grenades or hard breach charges as secondary gadgets.

Shield Rework

The much anticipated Shield rework, which was released in the LAB Test Server, is finally coming with the new season. Shield-wielding operators like Montagne, Blitz, and Fuze can no longer hip-fire. However, they can now sprint with their shields and burst through barricades swiftly, as well as throw grenades, reload, or activate their gadget without lowering their shield.

Additionally, the new free-look ability allows them to look around corners of a door, for traps or lurking operators. Note: Osa and Clash are not affected by this rework.
