Wesker's Message is a file that can be found in Resident Evil: The Darkside Chronicles.
A message carved by Wesker himself.
It reads: I won this game
I won this game（このゲームの勝者は私だ）
The message appears in the ending of Game of Oblivion 7. The message was carved onto a pillar, which caused Chris Redfield to realize when Claire Redfield expressed confusion about his disappearance that Steve Burnside's corpse had been stolen by another party. In addition, a S.T.A.R.S.-issue knife was also stuck on the "e", with Claire noting that it was similar yet different from Chris's own knife, with Chris simply remarking that he thinks he knows who its owner was while glaring at the knife, implying that he had deduced Wesker's survival from the Mansion Incident and was most likely the one who stole Steve's corpse.
