Get Your Marathon Contracts Done and Stop Letting Objectives Slow You Down
Contracts in Marathon aren't always the problem, but when they start piling up that things get frustrating. You've got faction obligations pulling in different directions, objectives that don't fit how you want to play and a session timer that doesn't care about any of that. The boost sorts it out.
KingBoost's boosters have run enough contracts to know the fastest routes through every objective type. No guessing, no wasted runs. You select the amount and we get moving.
50,000+ players trust us. That number isn't luck—it's the result of years of consistent delivery, professional boosters and a support team that cares about your experience.
Here's what makes us the best at what we do:
If you have any questions about the chosen service, reach out to us via LiveChat. Our operators will be happy to assist you.
Place your order with all necessary options selected.
Once we receive your order, we’ll contact you on Discord to confirm details, such as your preferred start time.
If you selected the Piloted boost method:
Our professional booster will play on your account following all possible safety measures (e.g., VPN) according to the agreed schedule.
Please avoid logging into your account while the boost is in progress. If you’d like an update, feel free to message your booster directly on Discord or contact our support via LiveChat.
If you selected the Selfplay (Remote) boost method:
We’ll ask you to install Parsec — a trusted and widely used program we work with for this method.
Our booster will connect remotely to your PC and complete the boost according to the set schedule.
While this method may seem a bit more technical, it offers the highest possible level of safety.
Once the order is complete, we’ll notify you, then you’ll be free to log in and enjoy the results.
We will highly appreciate it if you leave a review on our Trustpilot page!
Yes. The boost is tailored to the specific objectives you select. You're not getting random contract completions - you're getting exactly what you pick when you order.
Start time is within 15 minutes of purchase. Full completion runs around 2 hours 30 minutes depending on the contracts selected and how many runs you've ordered.
Great staff, quick turnaround and completion.
Very Top and quickly
Great communication. Perfect runs
Great experience
Scoring 3,400 on Key Plus was impressive, especially since it’s one of the most challenging endgame tasks. The group managed to breeze through it in a single day, proving they are still the best service choice of all time.
