Regen V4

Regen V4 is a superior tier head implant in Marathon that provides +50 Self-Repair Speed and +20 Revive Speed, pushing both regeneration and revival capabilities to near-peak levels. The +50 Self-Repair Speed at superior rarity means passive health regeneration kicks in fast enough to carry runners through back-to-back fights with minimal consumable use, a significant survivability advantage in extended raids. The +20 Revive Speed makes reviving downed teammates meaningfully quicker, reducing the vulnerable window during a revive animation in contested areas. Regen V4 has no stat penalties, maintaining the series' clean modifier profile throughout its tier progression. For squad-focused runners in high-difficulty zones, this implant provides exceptional value by simultaneously strengthening personal durability and team recovery speed.
