How to set up your order
Platform is required: choose PC, PlayStation or Xbox. The Completion method is Piloted, meaning a verified player farms the keys on your account, so please stay logged out until it is done. Logins go through the encrypted form on the order page, never chat.
Under Keys, choose the Lab key (Cryo Archive 06), Secret Cargo (05), Monitoring (04), Pump Station (03), Generator (02), Maintenance (01) or the Lockbox Key x3 bundle, then set the quantity. Later vault keys cost more.
Extras gives you Express for a better queue spot and Super Express for the highest queue priority. Timing is confirmed in order chat before work starts.

Frequently asked questions
Which Marathon keys can I order?
You can order Lockbox Key x3 and the six Cryo Archive keys, Maintenance through Lab, and combine them in one order.
Do I need to stay offline?
Yes, avoid logging in until the order is finished, since the keys are farmed on your account.
Will the keys work in my raids?
They are delivered to your stash for use inside raids, and the assigned player confirms completion in order chat.
Is there a warranty?
Yes, after your order is completed: 8 business days, or 2 business days when a top-rated booster completes it. Some top-rated boosters offer their service without a warranty. Your order page shows exactly which applies as soon as a booster is assigned; if it shows no warranty and you want one, ask support for a different booster before the work starts.
Is it safe?
FullBoosts assigns verified players and protects piloted-service logins with an encrypted form on the order page. Only you and your assigned player can access those credentials while the order is open; they are erased when the order closes or a dispute is opened. Keep logins out of chat. Where Self-play is available, you play together and keep control of your account. Every delivered order has a 72-hour review window.
