Sprint Kit V4

Sprint Kit V4 is a superior tier head implant in Marathon that brings elite-level Agility, Fall Resistance, Heat Capacity, and Loot Speed bonuses, and introduces the "Energy Reservoir" perk: when the runner uses an Energy Amp, energy is shared with nearby crew members. This perk transforms Sprint Kit V4 from a personal mobility implant into a squad-support tool, rewarding runners who carry Energy Amps with the ability to benefit their whole team while also enjoying the series' best mobility stats at this rarity. Superior rarity places this implant in high-value territory, making it a priority acquisition for mobility-focused runners who also want to contribute to crew sustain. The Energy Reservoir perk pairs well with coordinated squad play in high-density threat areas. Sprint Kit V4 is the first implant in the series where its value extends clearly beyond individual performance.
