Gameplay Mechanics

Turn-Based Combat Fundamentals

Zero Company uses a classic turn-based tactics structure similar to XCOM. You control a squad of up to four operators per mission. Each turn, you issue all your commands, then the enemy takes their turn. Understanding the action economy is the key to survival.

Action Points (AP)

Every operator receives 3 Action Points per turn. These can be spent on:

• Movement — Short moves cost 1 AP, longer dashes cost 2 AP. You can split movement around other actions.
• Attacks — Standard shots typically cost 1-2 AP depending on the weapon. Heavy weapons and special attacks cost more.
• Abilities & Items — Grenades, medkits, and class skills each have their own AP cost.
• Overwatch — Setting a reaction fire cone costs AP based on cone length and number of shots.

Advantage Points (Shared Squad Resource)

Your squad shares a pool of Advantage Points that accumulate with every successful hit on enemies. These are not per-character — they belong to the whole squad and can be spent by anyone.

Advantage Points power high-impact abilities including:

• Rocket barrages from Heavy operators
• Heavy blaster volleys that disorient enemy squads
• Class-specific ultimates and special maneuvers
• Call for Backup — a bonded teammate automatically follows up your attack

Because Advantage Points are shared, it's often worth having lower-damage operators build the pool so your heaviest hitters can spend it on devastating finishers.

Cover, Sightlines & Destruction

Positioning determines survival in Zero Company. The battlefield uses a cover system with three states:

• Full cover — Significantly reduces enemy hit chance. Operators behind full cover are very hard to hit from the front.
• Half cover — Moderate hit chance reduction. Useful but not safe against determined enemies.
• No cover (flanked) — Exposed operators take massive accuracy penalties and are vulnerable to critical hits.

Destructible Cover

Not all cover is permanent. Some objects — crates, barriers, certain walls — can be destroyed by explosives and heavy weapons. This creates tactical opportunities:

• Blow up cover to expose entrenched enemies
• Create new sightlines for your Sharpshooters
• Deny safe positions to advancing enemy squads
• Chain explosions for area damage when enemies cluster near destructible objects

High Ground & Flanking

Elevated positions grant accuracy bonuses and expanded sightlines. Flanking an enemy — attacking from an angle where their cover doesn't apply — negates their cover bonus and can trigger critical damage. Always look for ways to reposition and attack from unexpected angles.

Overwatch: Reaction Fire

Overwatch is one of the most important defensive tools in Zero Company. Instead of acting immediately, an operator can set an adjustable cone of reaction fire that triggers when enemies move or take actions within it.

How Overwatch Works

• Cone length affects accuracy — Longer cones cover more area but reduce hit chance. Short cones are deadly accurate.
• Invest AP for more shots — Spending additional AP lets the operator fire at multiple enemies who enter the cone.
• Movement interruption — Enemies hit by overwatch while moving may have their movement stopped mid-action, wasting their turn.
• Chance-to-hit varies — Your overwatch accuracy is displayed when placing the cone, based on cone length and operator stats.

Permadeath & Injury System

Zero Company features permadeath by default, but the system is more forgiving than it first appears. Understanding the injury mechanics is essential to keeping your squad alive.

The Three-Strike Rule

1. First downing — Operator falls and enters the Injured state. A teammate can move adjacent and spend 1 AP to "rally" them back into the fight.
2. Second downing — The operator goes down again, still revivable, but their Injury penalties stack and they're increasingly vulnerable.
3. Third downing — The operator is killed in action permanently. You can visit their name on the memorial wall at The Den.

Injury Penalties

Each time an operator is downed and revived, they accumulate Injury stacks that reduce their combat effectiveness — lower accuracy, reduced movement, or impaired abilities. Injuries persist through the mission and make subsequent downings more likely.

Medic vs. Non-Medic Revives

This distinction is critical:

• Non-Medic rally — Restores only a fraction of the operator's health, leaving them exposed and likely to go down again.
• Medic rally (First Responder passive) — Restores the operator to full health, dramatically reducing the chance of a repeat downing.

This is why running a Medic in every four-operator squad is the single most effective structural decision for avoiding permadeath.

Hawks Is Exempt

Your protagonist Hawks cannot permanently die. If Hawks goes down, the mission immediately restarts from the beginning. This means you should always prioritize protecting Hawks — losing a mission because the commander fell is far worse than losing a single operator.

Can You Disable Permadeath?

Yes. Bit Reactor allows players to toggle permadeath off in the settings. If you want to experience the story without the stress of permanent character loss, you can play with permadeath disabled. This does not affect difficulty in other ways.

The Bond System

The bond system is Zero Company's most distinctive feature and what sets it apart from XCOM. Operators who fight together develop relationships that unlock meaningful gameplay benefits.

How Bonds Form

Deploy the same pair of operators together repeatedly, and their bond level increases over time. Bonds form through shared combat experiences — not just proximity, but actual cooperation in the field.

Bond Benefits

• Cross-training — High-bond operators can learn abilities from each other's classes. A Heavy might pick up a Medic skill, or a Scout might learn a Soldier ability.
• Call for Backup — A bonded teammate can automatically follow up your attack with a strike of their own, creating devastating combo turns.
• Combat synergy bonuses — Bonded pairs gain passive accuracy and damage bonuses when operating near each other.
• Story moments — Bonds unlock unique dialogue and character moments that deepen the narrative.

Even Rivals Can Bond

Not all relationships start friendly. Characters like Trick (a clone trooper) and Luco Bronc share a bitter history from the Battle of Umbara. Despite their ideological conflict, deploying them together can still build a bond — though the path to trust is longer and the story payoff is different.

Base Management: The Den

The Den is your mobile base of operations and the hub between missions. Here you manage every aspect of Zero Company outside of combat.

What You Do at The Den

• Recruit operators — Hire new mercenaries with different species, classes, and backstories
• Customize your squad — Adjust appearances, voices, specializations, and talent trees
• Upgrade gear — Purchase and equip new weapons, armor, and accessories
• Train skills — Spend resources to unlock new abilities and passive bonuses
• Nurture bonds — View relationship progress and trigger character interactions
• Prepare for missions — Select your four-operator squad and loadout before deployment

Progression Loop

The core loop is: Mission → The Den → Mission. Completing missions earns resources, increases bond levels, and unlocks new training options. The Den is where you transform raw recruits into a coordinated, bonded fighting force.

Mission Structure & Replayability

Each mission presents different objectives — infiltration, assault, rescue, sabotage, and more. The outcomes of your decisions make each playthrough different:

• Branching choices — Some decisions affect the story and which characters stay with you
• Procedural elements — Enemy placements and battlefield conditions vary
• Multiple squad compositions — Different class and species combinations create unique tactical approaches
• Bond-driven stories — Which characters bond and which stories unfold depends on your deployment choices
