Biotoxic Disinjector Boost - Marathon's First Contraband Weapon, Extracted For You
The Biotoxic Disinjector is the first Red Rarity weapon in Marathon and it's not something you stumble into. Getting it means completing all seven Vaults in Cryo Archive, collecting six AI Subroutines across multiple runs, solving a DNA puzzle, maintaining Security Clearance throughout and then actually killing The Compiler in Vault 7. This is a coordinated team effort with raid-level mechanics where one mistake can cost you everything you brought in. The Compiler fight itself has multiple damage phases, terminal matching puzzles and add waves that will overwhelm a squad that isn't communicating. And if you die without self-revives, that's it, your gear is gone.
The weapon is worth the trouble though. Two fire modes: a laser beam and a fully automatic grenade launcher that shreds through Runner Shells. 2,000 charges total, 1,000 per magazine, and each grenade shot only costs 22 charges. Nothing else in Marathon comes close.
KingBoost's team clears the full Vault 7 encounter, defeats The Compiler and extracts the Biotoxic Disinjector to your account. You also receive the Compiler Ganglion boss drop, AI Subroutines and all Salvage collected during the run.
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!
Cryo Archive is Marathon's pinnacle PvE content. Vault 7 requires completing all six previous Vaults and collecting their AI Subroutines, which can take multiple runs across weekends. The Compiler fight itself has raid-style mechanics that punish uncoordinated teams.
That's the risk with Marathon. Death without self-revives means losing what you brought in. Our team handles the run so your loadout stays safe.
An additional CyberAcme contract completed during the Cryo Archive run for extra unique rewards.

Been using these guys for years. Amazing prices and fast service. Keep up the great work
Wowww Kingboost is very professional and trustworthy. I was looking for a custom order Booster to complete limited time skin challenge on Fortnite, John Wick Simpsons. And theres quite long to find a suitable booster for this custom order, but it's my fault I canceled it because I'm having paranoia because of the thin limited time. Asked for a refund by my fault, from the customer service and it takes only 2 Business days the money entered my bank account again. Wow Kingboost is very professional even it's my impatient fault and paranoia. Ty Kingboost, u guys rock!
