Frequently asked questions
What rewards can I expect from Echoes of War?
On first-time clears you receive Oroberyl, Advanced Cognitive Carriers and Marks of Perseverance, and earning all stars also improves your seasonal rating and unlocks titles.
Do I need strong operators for this boost?
Yes. The player works with your own roster, so it needs solid operators, weapons and gear for the difficulty.
Is Echoes of War a limited-time mode?
No, it is a permanent mode, but its combat stages rotate by season with special mechanics.
Can I play while the boost is running?
Please stay logged out until the order chat confirms completion, since the player is using your account.
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.
