By this time, all six(!) trophy skins have been sent out to their respective winners with the 3.23.6.0 Update. I’d like to thank the WeslieG for hosting this event, and the players who participated in it.
Trophy skins require a game update to distribute, hence the longer wait between the even’t end and everyone actually receiving their skin.
If you participated in the event and haven’t received the forum badge for doing so, this can still be claimed at any time: Competitive Solo PVP Survival Event Badge
