Modern Warfare 4 arrives on October 23, 2026, but you do not have to wait until launch day to start collecting its cosmetics. A limited-time event in Black Ops 7 Season 5 lets eligible players unlock two Universal Weapon Camos through connected progress across Black Ops 7 and Warzone. If you are planning to sharpen your aim in MW4 Bot Lobbies, the event is also a useful way to prepare. The key details are simple: buy a qualifying digital pre-order, claim Moonlit Pearl, then earn 5,000 Skulls for Gilded Ruin.
Digital Pre-Order Comes First
The event lasts 90 days, but access is tied to a digital Standard or Vault Edition pre-order. Once the purchase appears on your Activision account, Moonlit Pearl and the Hunter Killer Operator skin should become available through the promotional section of Gunsmith. Physical pre-orders do not unlock the camo challenge, even if a retailer provides an Operator code. Make sure the pre-order and your current Call of Duty games use the same account before you start playing.
How the Skull Challenge Works
Gilded Ruin requires 5,000 Skulls, earned by eliminating enemies in Warzone, Black Ops 7 Multiplayer, Endgame, or Zombies. Progress is shared, so you can switch modes whenever the grind starts feeling stale. Warzone is the quickest route on paper, while Multiplayer is a better fit if you want practice for Modern Warfare 4. Endgame and Zombies work well for players who would rather fight AI and take a steadier pace.
Chasing the Serialized Reward
The first 100,000 players to reach 5,000 Skulls receive a numbered version of Gilded Ruin, with an engraving from 000001 through 100,000. Miss that cutoff and you will still receive the animated camo, just without the number. Players hunting for a serialized copy should focus on Resurgence, Warzone Casuals, or busy Multiplayer playlists such as Hardpoint and Domination. Zombies is reliable, but one Skull per elimination makes it a poor choice for a race.
Carry Your Camos Into MW4
Moonlit Pearl is available as soon as the pre-order is registered, and Gilded Ruin can be used in supported current titles after the challenge is complete. Both cosmetics are expected to carry into Modern Warfare 4 on launch day. They will not transfer old weapons, attachments, or levels, though. You will still need to build and level MW4 weapons yourself, so use the event to practise movement, target tracking, and quick decision-making before October. Players who want a faster preparation route can also look into buy Bot Lobbies MW4 while keeping their Activision account details consistent.
