Unlock the Cores That Define Your Build!

Cores are what separate a stock Runner Shell from a finely tuned machine in Marathon. These Shell-specific upgrades enhance your abilities in ways that completely change how you approach fights and extractions. A Destroyer with Impact Siphons turns incoming barricade damage into shield energy. A Thief with the right Core gets a second Grapple Device charge. Cores don't just drop on demand, they require credits to unlock and specific farming routes to acquire them efficiently and the Prestige-tier Cores like Impact Siphons cost 2,500 credits each.

Kingboost’s boosters know the efficient Core farming routes and will unlock whichever Cores you need for your preferred Shell. Whether you're building out a Destroyer for frontline aggression or hunting down mobility Cores for your Vandal, we handle the progression while you keep the loot priority on everything that drops.

YOU WILL GET

  • Core progression and unlocks
  • Loot priority – everything belongs to you
  • Efficient Core farming routes

Just finished my 6th order on this site…

Just finished my 6th order on this site and honestly, everything is perfect as always. I keep coming back here bc the service is just solid every single time. The support team is super fast, they usually reply to me in like 30-60 seconds. Every time I had a question or was a bit confused about something, they helped me out and fixed it instantly. Btw, it’s really nice that u don’t have to wait ages for an answer, hahah 😂 Definitely recommend these guys if u need any help with ur games :)
