Iron Nest Unlocks: Medals & Ammo Progression

Progression in Iron Nest is carried by mission completion and requisition credits: as you clear missions you earn credits to spend on the 21 shell types in your supply truck.

Progression in Iron Nest is carried by mission completion and requisition credits: as you clear missions you earn credits to spend on the 21 shell types in your supply truck.

You do not "level up" a character; instead you unlock the right to field heavier or specialized rounds (HE, AP, Smoke, Illumination, WP, chemical, Atomic, PRPG) as the campaign and your credits allow.

Early missions let you train cheaply with 3-credit Drill rounds, while late, high-stakes shots may call for the 666-credit Atomic shell that ends the city in the Atomic ending.

Credits are the soft gate: a tight requisition means you buy the lightest shell that completes the objective, which is the core strategic choice of the sim.

Because Iron Nest is single-player, unlocks are local to your save and tied to the missions you have finished, not to an online account or seasonal battle pass.

Plan your unlocks around the next mission's target type — armor wants AP, infantry clusters want HE or WP, night wants Illumination — so credits are never wasted.
