local MarketplaceService = game:GetService("MarketplaceService")
local Players = game:GetService("Players")
local passID = 1681891408 -- Change this to your Pass ID

local function onPromptPurchaseFinished(player, purchasedPassID, wasPurchased)
if wasPurchased then
local ownsPass = MarketplaceService:UserOwnsGamePassAsync(player.UserId, passID)
if ownsPass then
print(player.Name .. " purchased the Pass with ID " .. passID)
-- Kill all players
for _, player in ipairs(Players:GetPlayers()) do
local character = player.Character
if character then
local humanoid = character:FindFirstChildWhichIsA("Humanoid")
if humanoid then
humanoid.Health = 0
end
end
end
end
end
end

-- Connect "PromptGamePassPurchaseFinished" events to the function
MarketplaceService.PromptGamePassPurchaseFinished:Connect(onPromptPurchaseFinished)
