Sergeant Ostrovsky is a character that appears in S.T.A.L.K.E.R.: Call of Pripyat.
Events of Call of Pripyat
When Major Alexander Degtyarev meets the survivors of Operation Fairway in the abandoned city of Pripyat, Ostrovsky is among the few who survived the repeated Monolith attacks. He is seen sitting in the upper floor of the Laundromat, near Valyushok. Like most of the soldiers, he cannot be interacted with; instead, if the player attempts to speak with him, he will advise the player to speak to Kovalsky.
While Degtyarev, Tarasov and his squads are sent by Kovalsky to the hospital to recover the Gauss gun from the Preacher, Klimenko and his squad (comprised of Ostrovsky, Sergieyev and Valyushok) are sent in patrol by Kovalsky. When Degtyarev report the death of Morozov and the mysterious weapon he found, Kovalsky receives a message from Klimenko. During the brief broadcast, Klimenko requests help before the radio shuts. Receiving no further reply, Kovalsky asks Degtyarev to investigate.
Degtyarev then goes to their last location, where he find the bodies of all four soldiers, seemingly shot, despite no enemies around. When Degtyarev finds out the squad sighted Monolithians in the area, Kovalsky suggests that they were killed by them, and asks Degtyarev to raid the Bookstore (if it had not been done already) which serves as an outpost for the Monolith.
Later, when Degtyarev is sent by Kovalsky to rescue Stetsenko, and is forced to confront a Controller, Kovalsky theorizes the squad encountered the said mutant, and was forced by it to shoot themselves.
- His body never disappears, which means the player can use it as a stash of some sort.
