Key Osa facts (Y11S3)

Deployable on floors, doors and windows; deploying smashes the barricade; can be placed while rappelling; shield does not fully cover a doorway.
Y11S3.2: deployment restrictions reduced. (since Y11S3.2)
Canister at the base on Osa's side destroys it; explosives (Nitro, Impacts, frags) break it; a melee hit makes it opaque.
Noor's Horus Lance burrows through a deployed Talon and shatters it opaque. (since Y11S3)
Castle panels and Goyo barricades block placement on that door/window; fire and gas push attackers off it.
Not electronic or remote: Mute, Bandit and Thatcher-type gadgets do not touch it, which is why she is used to cover plants against Mute.
Pro presence: played in 1% of all rounds in SiegeGG-tracked matches (time window not stated, likely cumulative, so older operators are favoured). (since siege.gg, read 2026-10-20)
