Beast Force Guide (2026) — Tips, Kaiju Powers, Codes & Strategies
Kaiju are tearing through the city, and the only thing standing in their way is you and the Defense Force. This 2026 guide breaks down how Beast Force actually plays — the hunting loop, weapons and armor, the Beast Cells and Yen economy, the No.8/No.9/No.10 Kaiju powers, and every working code.

What Is Beast Force in 2026?
Beast Force is an action game on Roblox by the developer MustacheDev, inspired directly by the manga and anime Kaiju No. 8. You join the Japan Anti-Kaiju Defense Force to stop kaiju — the game calls them "beasts" — from leveling the city. You are armed with the military's weapons and artillery, but the twist that gives the game its identity is that you can also harness Kaiju powers and fight the monsters using their own abilities.
As of June 2026 the game is in active development, running as a pre-alpha public test, so content, weapons, and Kaiju powers are still being added on a regular cadence. That early-access status is also why codes drop multiple times per month: the developer hands out currency to keep testers engaged between updates. You can play it directly on Roblox.
The Core Beast-Hunting Loop in Beast Force
The loop is simple to describe and satisfying to grind. You start at the military base camp, where you pick your weapons and armor. From there you leave the safety of camp to hunt beasts out in the combat areas. Every beast you defeat drops valuables, and you exchange those valuables for cash back at camp. That cash buys new weapons, better armor, and access to new map areas where the next tier of beasts waits.
It is a classic gear-up, hunt, sell, upgrade cycle, and like every loop of that kind it compounds. Better gear lets you kill tougher beasts faster; tougher beasts drop more valuable loot; more loot funds the next upgrade; and the next map area opens up. The whole game is about keeping that flywheel spinning without getting stuck fighting beasts that out-scale your current weapon.
It helps to think of every session in three phases. The gear phase at camp is where you redeem codes, cash in your loot, and decide what to buy. The hunt phase is where you actually fight beasts and collect drops. The cash-in phase is the return trip where you bank everything and reinvest. Most wasted time comes from skipping the gear phase — rushing out underprepared into beasts that simply take too long to kill.
Why Early Map Areas Matter
It is tempting to push toward the hardest beasts as fast as possible, but the early map areas exist for a reason. They let you learn beast attack patterns cheaply, with low risk, while you build up the Yen and Beast Cells to afford gear that makes the harder zones survivable. Many new players stall not because they lack skill, but because they pushed into a high-tier area with low-tier gear and spent twenty minutes chipping at a beast that should have taken seconds.
Weapons and Armor in Beast Force
Your two gear slots — weapon and armor — decide everything about how a hunt feels. The weapon controls how fast you delete beasts; the armor controls how many hits you can eat before you go down. Beast Force gives you military hardware to start, ranging from standard firearms to heavier artillery as you progress, and balancing the two slots is the core gearing decision.
Buy Damage and Survivability Together
A common mistake is dumping every Yen into the biggest weapon you can afford and ignoring armor entirely. A glass-cannon build kills beasts quickly right up until one combo drops you, at which point you lose your hunt and your time. Keep your armor roughly in step with your weapon so you can actually stay in the fight long enough to use that damage.
Match Your Weapon to the Beast
Different beasts reward different approaches. Fast, swarming beasts get melted by rapid-fire weapons, while big, tanky beasts want concentrated single-hit damage or artillery. As your arsenal grows, keep a couple of options in mind rather than relying on one gun for every encounter — the right tool turns a grinding fight into a quick kill, and quick kills are what keep your income high.
Beast Cells & Yen Economy in Beast Force
Beast Force runs on two currencies, and understanding the split is the single most useful thing a new player can learn. Yen is your everyday cash: you earn it by selling the valuables that defeated beasts drop, and you spend it on weapons, armor, and map access. Beast Cells are the rarer, more valuable currency, tied to unlocking Kaiju powers and the deeper content. They are also exactly what most codes hand out, which makes redeeming codes the most reliable way to stock up.
Redeem every code before you spend. While the game is in testing, codes are the fastest Beast Cell source by a wide margin — far quicker than grinding for them. Stack them up on a fresh account and you start with a real head start toward your first Kaiju power.
Reinvest Yen, don't hoard it. Yen sitting in your wallet does nothing. Every time your bank grows enough for the next meaningful weapon or armor upgrade, buy it — the faster kills it enables pay the cost back quickly. The only reason to sit on Yen is if you are a small step away from unlocking a new map area that is clearly worth saving for.
The mental model that keeps your economy healthy is straightforward: Yen scales your hunting power, Beast Cells scale your ceiling. Spend Yen freely to keep killing beasts faster, and treat Beast Cells as the precious resource you bank toward Kaiju powers. Mixing the two up — hoarding Yen or burning Beast Cells on the wrong unlock — is what stalls most early runs.
Where Income Actually Comes From
Because Yen comes from selling beast drops, your income is tied to kill speed and beast value. A beast in a higher map area drops more valuable loot than a low-tier one, so the fastest way to grow your bank is to be hunting the toughest beasts your gear can comfortably handle — not the easiest. The sweet spot is the highest area where your kills still feel fast; push past it and your income actually drops because each kill takes too long.
Kaiju Powers: No.8, No.9, and No.10 in Beast Force
The headline feature of Beast Force is that you do not have to fight kaiju purely as a human soldier — you can harness Kaiju powers and turn their abilities against them. As of June 2026 the available powers are No.8, No.9, and No.10, each tied to the corresponding kaiju from the source material and unlocked primarily with Beast Cells.
Kaiju powers change how you fight. Instead of relying only on military weapons and artillery, a Kaiju form gives you a kit of monster abilities that can clear beasts in ways guns cannot. This is the main long-term goal for most players: bank enough Beast Cells through hunting and codes, then unlock a power that fits how you like to play. Because the game is in active development, expect the roster and the balance of these powers to keep shifting as updates land.
Beast Force Tips and Strategies
Beyond the loop, a handful of habits separate players who progress smoothly from those who stall out. Here is what actually moves the needle.
Redeem codes the moment you log in. Codes expire and rotate constantly in a game that updates this often. Make checking our codes list the first thing you do each session so you never miss a Beast Cell drop.
Hunt the highest area you can clear fast. Your income peaks at the toughest beasts your gear still kills quickly. If kills are starting to drag, you have over-pushed — drop back a tier and upgrade before you climb again.
Keep weapon and armor in balance. A run ends the instant your character drops, so survivability is income too. Do not let your armor fall a full tier behind your weapon.
Save Beast Cells for Kaiju powers. It is the rare currency for a reason. Resist spending Beast Cells on anything you could have bought with Yen instead.
Learn beast patterns in safe zones. The early map areas are a free training ground. A few minutes learning when a beast winds up its big attack pays off for the rest of your account's life.
Common Beginner Mistakes
New players lose time the same handful of ways. The most common is ignoring codes and grinding Beast Cells the slow way when free ones are sitting right there. A second is over-investing in weapons and skipping armor, which turns every tough beast into a coin flip. A third is pushing into high-tier areas too early, where beasts out-scale your gear and your income actually falls. Finally, do not trust shady "free Beast Cells" sites or scripts — the only legitimate free currency comes from the in-game redeem menu, and anything asking for your password or Robux is a scam.
