OPERATOR FILES — PERMANENT PROGRESSION

OPERATOR UPGRADES

Each run earns Casings. Casings buy upgrades. Upgrades change how every future run plays. Permanent. Stackable. Irreversible. Build your operator the way field experience demands — not the way command intended.

▸ FIELD CURRENCY

WHAT ARE CASINGS

// FIELD LOG — CLASSIFIED

In the field, there are no medals. No promotions. No paperwork filed in triplicate for a job that never officially happened.

When you've survived long enough to count the empty shells at your feet — that's your receipt. Operators call them Casings. Every spent round that connected. Every kill that kept you breathing. Every wave you walked out of when physics said you shouldn't have.

They add up. And out here, they spend.

// HOW TO EARN CASINGS

  • Enemy KillsEvery kill drops a small casing reward. Elite enemies and bosses drop significantly more.
  • Wave CompletionSurviving each wave earns a wave-end bonus. Longer runs compound your casing income exponentially.
  • Milestone WavesEvery 10th wave (Wave 10, 20, 30…) triggers a Milestone Bonus — a major casing reward for veterans who push deep.
  • Scavenger UpgradesUpgrade the Scavenger meta-perk to increase loot multipliers — and collect even more casings from fallen enemies.

▸ AVAILABLE TO ALL OPERATORS

UNIVERSAL UPGRADES

Six permanent upgrades that benefit every operator equally. Build your foundation here before committing to operator-specific investments. These compound across every run, every character, every wave.

Veteran Constitution
Common
VETERAN CONSTITUTION
Max HP +15 per level. Stacks with every in-run HP upgrade you find. At max level you start each run with +90 permanent HP — a full extra health bar.
⬡ 12 CASINGS / LEVEL
Field Medic
Uncommon
FIELD MEDIC
Health pickups restore +10 extra HP per level. Elite and boss kills drop more health — the bonus stacks fast during sustained high-wave engagements.
⬡ 16 CASINGS / LEVEL
Scavenger
Uncommon
SCAVENGER
Loot drop chance +15% per level. More weapon drops, more ammo boxes, more health packs. At max (+30%), you'll rarely run dry past wave 40.
⬡ 20 CASINGS / LEVEL
Rapid Reload
Common
RAPID RELOAD
All weapons start with +20% larger magazines per level. Ammo pickups restore even more. Especially brutal with the Minigun and Flamethrower on long boss waves.
⬡ 16 CASINGS / LEVEL
Fortified Hide
Rare
FORTIFIED HIDE
Start every run with +25 Shield HP per level. The shield absorbs the first hits and stacks with in-run Reinforced Armor upgrades. At max level: 100 shield before wave 1 begins.
⬡ 28 CASINGS / LEVEL
Tactical Training
Epic
TACTICAL TRAINING
XP gain +15% per level. More XP means more in-run upgrades, sooner. The snowball compounds — at max (+45%) you hit your build's power spikes far earlier every run.
⬡ 40 CASINGS / LEVEL

▸ CHARACTER-EXCLUSIVE PROGRESSION

OPERATOR EXCLUSIVE

▸ RARITY CLASSIFICATION

FIVE TIERS

Upgrades are classified by rarity — from field-standard Common to the devastating Mythic tier. One Mythic upgrade exists per operator. Save up. It changes the run entirely.

COMMON
Foundation stats.  Straightforward bonuses — more HP, more ammo, shorter cooldowns. Cheap to buy, powerful to max out early.
UNCOMMON
Utility upgrades.  Better loot, extra healing, improved resource drops. The upgrades that make your average run more consistent across the board.
RARE
Build shapers.  Strong synergies between your operator's kit and weapon upgrades. Each Rare unlock starts to define how your operator plays in a run.
EPIC
Identity upgrades.  These lock in a playstyle. Commando's Ghost Operative companion. Soldier's turret buffs. Guerrilla's mine mastery. Expensive — worth every casing.
MYTHIC
One per operator. Run-defining power.  Not an upgrade — a transformation. Each operator's Mythic rewrites the rules of how they fight. 180 Casings. No refunds.
⬡
// MYTHIC EXAMPLES Commando's WRAITH PROTOCOL: while cloaked, deal 3× damage and move 25% faster.  ·  Marine's UNYIELDING FURY: during Adrenaline Rush, deal 4× damage and take 60% less.  ·  Guerrilla's APOCALYPSE: detonate all mines simultaneously, leave lava on the ground for 8 seconds.

▸ THE LOOP

HOW IT WORKS

Permanent upgrades persist across every run. The more you play, the stronger each run starts. There's no reset, no prestige, no catch. You earned it — it stays.

01
RUN
Pick your operator. Enter the field. Every kill earns Casings — passive income from the moment the first wave spawns.
02
EARN
Casings accumulate through kills, wave completions, boss takedowns, and milestone bonuses. The further you push, the more you earn.
03
SPEND
Open the Operator Menu between runs. Buy the upgrades that fit your playstyle. Universal first, then go deep on your operator's exclusive tree.
04
COMPOUND
Every upgrade stacks. Meta upgrades combine with in-run upgrades. The longer you invest in one operator, the further each subsequent run goes.

▸ START BUILDING YOUR OPERATOR

EVERY CASING COUNTS

The Operator Menu is open between runs. Study the upgrades. Build your strategy. When you know what you're building toward, the Casings start to feel like ammunition.
