Biogenic Alloy

Biogenic Alloy is a Prestige-tier salvage material formed from a fusion of biological and metallic compounds through a process that only becomes possible under the extreme environmental conditions found deep within Tau Ceti IV's most restricted zones. The resulting material is extraordinarily durable while retaining a degree of organic flexibility that no purely synthetic alloy can replicate. Multiple factions prize Biogenic Alloy for endgame upgrade nodes, particularly those focused on advanced runner augmentation and the integration of organic and mechanical systems. As one of the rarest salvage materials in Marathon, Biogenic Alloy drops primarily from the Cryo Archive and Prestige Locked Rooms. Runners who reach the endgame and can consistently access Prestige-tier loot sources will find Biogenic Alloy to be the defining bottleneck of the highest faction upgrade tiers.
