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.

Runs to master

▸ 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.

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.

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.

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.

Permanent perk, bought with Casings. Not the in-run Scavenger card from Field Command: that one only widens pickup reach and adds ammo drops for the current run.

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.

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.

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.

▸ CHARACTER-EXCLUSIVE PROGRESSION

OPERATOR EXCLUSIVE

Beyond the universal upgrades, every operator has their own deep tree of exclusive upgrades: built around their kit, their weapons, and their playstyle. Dozens of options. One mythic power that changes everything.

▸ RARITY CLASSIFICATION

FIVE TIERS

Upgrades are classified by rarity, from field-standard Common to the devastating Mythic tier. Every operator has two or three Mythic upgrades, plus a 600-casing second chance. Save up. They change 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

Run-defining power. Not an upgrade: a transformation. Each operator's Mythics rewrite the rules of how they fight. 85 to 180 Casings, and 600 for the ultimate second chance. 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 PREDATOR STRIKE: On-the-Move becomes +80%, your burn trail deals 25 damage per second and every dash triggers an instant knife.

▸ IN-RUN SYSTEM

FIELD COMMAND

Casings build the operator. Field Command builds the run. Every second level-up earns a pick, but the fight never stops for it. Picks are banked until you call them up. 25 general cards plus 6 cards of your own operator. Every card goes to LV5. Build it right or carry dead weight to wave 100.

NO PAUSE

BANKED PICKS

Level-ups don't freeze the field. Open your picks with Tab / View when you have a second, or they open automatically when the wave is cleared.

LOADOUT

6 GEAR · 3 SUPPORT

Stat upgrades take a Gear slot. Anything that puts something on the field (turrets, drones, mines, escorts) takes Support. Weapons take no slot, and neither does the Field Medic: he joins your squad. Slots full? From then on you're only offered level-ups of what you own.

CONTROL THE DRAW

REROLL · BANISH · SKIP

2 rerolls and 2 banishes per run, for upgrade cards (a weapon evolution is what it is). BANISH strikes a card from the run for good. SKIP isn't wasted: full ammo and 30% HP back.

YOUR OPERATOR

OWN CARDS IN EVERY OFFER

Every offer carries at least one of your operator's own cards while one is available. Six per operator, from Soldier's Discipline to Guerrilla's Punji Pits.

MYTHIC

OPERATOR EVOLUTIONS

Seven mythic evolutions: one per operator, and one for every operator's Medevac Drone. Max the base card to LV5 and its mythic takes over the same slot. Heavy Armor becomes Walking Fortress. Squad Leader becomes Elite Strike Team. Medevac Drone becomes Guardian Angel.

HEALERS

ONE HEAL CIRCLE

A gold circle round you: everything inside heals at once. The Field Medic joins any squad at LV3 without a slot and keeps your escorts on their feet. The Medevac Drone heals you first, and its mythic Guardian Angel also refills your shield and catches one lethal hit a wave.

MERGED

FEWER, STRONGER CARDS

Body Armor = Bullet Resistant + Blast Protection. Penetration = Bullet Penetration + Armor Piercing. Scavenger = Tactical Radar + More Ammo Drops: 330 px pickup reach at LV1, +40 px per level, more ammo drops. Ammo Refill and Weapon Upgrade cards are gone.

WEAPONS

EVOLUTIONS IN HAND

About every 8 levels a weapon evolution is banked. It always goes to the weapon in your hands. A weapon's mythic opens once it has all three normal evolutions. Max 2 weapon mythics per run.

INTEL

LOADOUT & FIELD REPORT

The LOADOUT tab in the pause menu shows every slot and level. The debrief ends with a Field Report: damage per source, so you know what actually carried the run.

STEAM DEMO

SAME SYSTEM, SMALLER POOL

The free Steam demo runs Field Command too. Some operator cards, legendaries, mythic evolutions and the Extra Life are full game only.

▸ IN-RUN SYSTEM

WEAPON EVOLUTIONS

Every weapon has a full upgrade chain: Rare, Epic, and Mythic. These aren't meta upgrades. Field Command banks a weapon evolution about every 8 levels, and it always goes to the weapon in your hands, so what you carry decides what evolves. The Mythic opens once a weapon has all three of its Rare and Epic evolutions, and it doesn't add numbers. It changes how the weapon operates entirely. Mythic weapon evolutions are full game only.

RARE

FIELD UPGRADE

Damage, fire rate, magazine, penetration. Straightforward gains that make the weapon more effective at what it already does.

EPIC

SPECIALIST MOD

Fundamental changes to the weapon's firing pattern, projectile behaviour, or special properties. Locks in a playstyle.

MYTHIC · MAX 2 PER RUN

OPERATING MODE

The weapon gains a new mode of operation. Rotating beams. Kill-triggered bursts. 360° shockwaves. Unlocks once the weapon has all three of its other evolutions.

▸ MYTHIC EVOLUTIONS · ALL 11 WEAPONS

PISTOL · FAN THE HAMMER

4× fire rate and at least 105 damage a round. Every pistol kill fires a 5-bullet burst in a 90° forward cone.

SHOTGUN · SHOCKWAVE ROUND

Every 3rd shot emits a 200-radius shockwave that hits all enemies in range. +20% damage.

MACHINE GUN · BULLET RAIN

Every bullet spawns two side lanes at ±20°. Side lanes deal 75% damage.

ROCKET LAUNCHER · HELLFIRE SEEKER

Rockets home in on the nearest active threat. +30% damage.

FLAMETHROWER · NAPALM RING

Every 4s of sustained fire: 8 large napalm blobs launch in a full 360° ring.

SNIPER · RAILGUN PROTOCOL

Bullets pierce all enemies and pass through walls. +50% damage. Full-auto fire.

GRENADE LAUNCHER · CLUSTER PROTOCOL

Each grenade explosion releases 5 sub-grenades (50% blast radius, 25% damage).

MINIGUN · LEAD WALL

After 1s of fire at full spin the stream opens into a wall of 5 parallel lanes. Outer lanes deal 60% damage.

LASER · OMNI PULSE

1s warmup → 6s of fast 360° beam, 2.5× damage, no heat → 13s cooldown. +30% damage.

ICE BEAM · ABSOLUTE ZERO

Frozen enemy deaths shatter: shards deal 45% of max HP to all units within 120px.

VORTEX CANNON · EVENT HORIZON

Vortex kills launch 8 radial projectiles from the kill point. +30% vortex DPS.

▸ 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.
