Marathon Thief Hunter/Killer Core: Grapple into a Hack

The Hunter/Killer is the Thief - Stealth's Deluxe core (not to be confused with Recon - Intel's core of the same name, which does something entirely different), and its premise is elegantly simple: grapple into a target, follow up with a melee or Knife - Melee strike, and that target is immediately Hacked. No prolonged X-Ray Visor aim time required. No positioning ritual. You close the distance with the Grapple Device, land the hit, and the Hack is done.

That's the whole read. But what makes it worth a Deluxe slot comes down to understanding why Hacking matters on a shell built around the Thief's kit -- and how this core turns a mobility tool into an offensive opener rather than just an escape route.

Our tier list rates the Thief S-tier for solo ranked. The kit is built around clean information, fast loot, and getting out ahead of trouble. The X-Ray Visor's base Hack -- achieved by holding your aim on a hostile -- costs time and demands you hold your aim on a threat. That's a liability in a live engagement.

The Grapple Device solves movement. Hunter/Killer turns that same grapple into your Hack delivery system, collapsing the gap between "I spotted a target" and "that target is compromised." The combo trades the careful visor-aim Hack for a fast, aggressive, close-quarters version. That's a different posture entirely -- and it suits players who want to use the Thief's mobility as an attack vector, not just an exit.

The Thief's passive trait, The Finer Things, rewards a full backpack with faster weapon handling and faster Grapple Device recharge. A loaded pack means your grapple cycles back faster, which means Hunter/Killer has more opportunities to fire per run. These systems point at each other.

Because Hunter/Killer commits you to melee range, your weapon choices matter more than on a passive build. You want something that wins close-quarters gunfights when the Hack doesn't end the engagement cleanly. The Bully SMG - SMG (15 damage, 540 RPM, Heavy Rounds, CQB) and the BRRT SMG - SMG both operate in the range bracket where this combo resolves. The Misriah 2442 - Shotgun shotgun is the more volatile option -- slower follow-up, but devastating at grapple-landing range.

For Cradle investment, the Dexterity track's Full Throttle' perk, at 14 total Energy, gives you Cardio Kick effects at the start of every run, a natural fit for a shell that wants to be moving constantly. The Endurance track's Quick Vent' perk, at 3 total Energy, is a low-cost entry point that helps you recover heat faster after the grapple-and-strike sequence, keeping your mobility available for the next rotation.

The Strength track is the one to consider if you lean into the knife specifically. "Close and Personal" at 11 total Energy / "Leech" at 14 total Energy reduces heat generated by melee and knife attacks. "Leech" at 14 Energy restores a small amount of health on knife hits. If you're committed to the knife as your primary Hack tool rather than a bare-hand melee, this track quietly supports that decision.

Hunter/Killer's real value is in engagements where you've already chosen to fight. Against a Runner who hasn't spotted you yet, a grapple-and-strike Hack is a decisive opener. Against a three-stack holding a chokepoint, the same move gets you killed in the air.

This core does not make the Thief into a brawler. It gives you one clean tool for converting a grapple into an information and pressure advantage. Play it as an opener, not a crutch -- hit the Hack, then use the disruption to either finish the engagement or break contact with a loaded backpack and a head start.

- Hunter/Killer converts the Grapple Device from a mobility tool into a Hack delivery system -- grapple in, melee or knife strike, target is immediately Hacked. The combo is fast and requires no visor-aim time. - Pair it with CQB weapons that win at the range you'll land at: the Bully SMG, BRRT SMG, or Misriah 2442 all close the engagement after the Hack lands. - Cradle investment in Dexterity (Full Throttle at 14 total Energy)" / "(Quick Vent at 3 total Energy) keeps your movement and heat recovery in sync with an aggressive grapple-and-strike rhythm.
