Choosing your side at the start

Step

In short Your first decision is which team to join, and your first action after that sets up everything else.

At the beginning of a match you pick either the human team, which holds eight players, or the demon team, which holds two. Humans need to start earning money immediately because every upgrade depends on it. One more thing to know before your first match: a human who gets eliminated mid-game can be converted to the demon side, which changes the balance on the field.

Pick a team join humans or demons.
Secure a room occupying a room right away is the first move for any human player.
Stack cash machines and gear factories put them in the same spot to generate more income from limited space.
Check your door the starting door is flimsy wood.

How humans survive the full 20 minutes

Check

In short Staying alive for 20 minutes requires a running economy, a tough door, turrets, and steady research progress all at once.

The human team wins by keeping at least one player alive for the entire 20 minutes. Eight players means eight people who need to divide up the work. Classes can be advanced to new stages, which is a separate progression from simple level-ups.

Economy is running cash machines and gear factories are placed and stacking income.
Room is secured you have occupied a room.
Door is upgraded past wood the wooden door falls too easily to hold for the full match.
At least one turret is placed automatic fire covers the base.
Weapons are being unlocked in order you work through the six legendary weapons toward the Horn of Counterattack.
Research is progressing advancing a human class to a new stage and pushing the main research line toward its maximum level both increase your team's power.

Running your economy as a human

Summary

In short Stacking money buildings in the same spot is how you fund every upgrade.

Every upgrade on the human side costs money. Cash machines and gear factories can be placed on top of each other, which lets you generate serious income without spreading across the whole map. Enemies also drop money when defeated.

Cash machine　generates money automatically; stack multiples for faster income.
Gear factory　a second type of money building; pairs with cash machines in the same tile.
Enemy drops　defeated demons leave money behind.

Door upgrades and why they matter

Table

In short The door separates the demons from your base, so the moment it breaks, the entire defense collapses.

The door separates the demons from your base. Upgrades run through multiple tiers, each costing more than the last.

Wood door	starting tier, breaks under demon pressure.
Mid-tier doors	bridge the early and late game with better durability.
Eternal Divine Gate	the highest tier, durable enough to hold against the demon's evolved attacks in the final stretch of the match.

Weapons, research, and turrets on the human side

Tips

In short Weapons, research, and turrets each add a separate layer of power.

Humans can unlock six legendary weapons during a match and they become available in sequence. The Horn of Counterattack is the last in the chain and the strongest, capable of taking down the demon's final evolved form. Research adds a separate layer of power: pushing the main research line to its configured maximum level completes your strongest upgrades, and finishing the Lethal Poison research line lets you convert demons using poison. Turrets handle enemies automatically.

Tips worth knowing

Unlock weapons in order — earlier weapons must be cleared before the later ones become available.
Target the Horn of Counterattack — it is the final legendary weapon and the one capable of stopping the strongest demon form.
Push your main research line to its maximum — that is when the most powerful upgrades unlock.
Research Lethal Poison if you want to convert demons — it requires one human to personally apply the poison to every original demon and then finish with a human victory.
Place turrets at base entry points — automatic fire slows demon pushes.

How demons close out a match

Tips

In short Demons grow more powerful as time passes, eventually reaching an evolved form.

Two demons cannot overpower a coordinated eight-person base in the early minutes. The demons grow more powerful as time passes, eventually reaching an evolved form that dramatically raises their strength. Breaking a room door is the clearest way to gain access and pressure the humans inside.

Tips worth knowing

Destroy room doors — a broken door gives you direct access to the humans behind it.
Coordinate with your partner — two demons hitting the same point at the same time are far harder to stop than two solo pushes.
Watch for the Mech — human players can deploy a Mech that deals damage to demons.
Push hard once your evolved form kicks in.

Redeem codes

Warn

In short Redeem codes the moment you find them, since they can expire and each one works only once per account.

The game has a code system that gives bonus items to anyone who enters a working code in the in-game menu. Codes can only be used once per account, and some carry expiration dates.

Worth watching out for

Codes are entered through the in-game menu.

Each code works only once on a single account.

Treat every code as time-sensitive expiration is possible at any time.

Common questions

FAQ

What should humans do in the very first minutes?

Place cash machines and gear factories immediately — without money you cannot afford any other upgrade. Stack them in the same spot to generate income faster.

Why can two demons beat eight humans?

Demons grow stronger the longer the match runs, and eventually reach an evolved form that dramatically increases their power. If the two demons coordinate a simultaneous push at that point, even a well-built base can fall.

What happens when a room door breaks?

A destroyed door lets demons walk directly into that room, which collapses the human defense in that area.

Can a human switch to the demon side during a match?

Yes — a human who is eliminated by a demon can be converted and finish the match fighting for the demon team. If the demons win while you are in that converted state, you share in the demon victory.

When do you get the Horn of Counterattack?

It is the last of the six legendary weapons, so you reach it only after unlocking the others in order.

What does advancing a human class to a new stage do?

Advancing to a new stage is a bigger jump than a normal level-up and increases your fighting power.
