Rim

CURRENTLY IN ALPHA, SOME FEATURES HAVE NOT BEEN FULLY TESTED FEEDBACK WELCOME! - UPDATED PAGE COMING SOON! - Check pinned comment for content creator applications

Giant monsters come out of the sea. You build giant robots and punch them back in.

Kaiju attack your coastline on a schedule, and every attack is a bit worse than the last, until you find the Breach on the ocean floor and blow it shut. In between, you build Jaegers, climb into the conn-pod and fight Kaiju up close. Since 1.4 they're all **film size**: a Jaeger stands 45 blocks tall, and Slattern stands 104.

| Fabric (needs Fabric API) | 1.20.1 to 26.3 |

| Forge | 1.20.1, and 1.21.1 to 26.3 |

New in 1.4: the Giants

• **Three times the size.** Jaegers and Kaiju are as big as they are in the films. They wade through the surf, leave footprints and flatten whatever they walk through.
• **Every Kaiju has its film move.** Leatherback's EMP, Otachi's acid and flight, Raiju's jaw, Slattern's throat lift and more .
• **Hit what you aim at.** Each body part has its own hit box. Hard enough blows tear limbs off, and that goes for both sides.
• **Canon finishers.** The right Jaeger can finish some Kaiju the way the film did.
• **Every Jaeger weapon rebuilt.** They have longer charge-ups, hit harder and look bigger.

**Updating from 1.3?** The title screen asks you once whether to go giant or keep the old size. Jaegers and Kaiju already in your world keep their size. You can switch later with "bodySize" in config/rim.json ("big" or "small").

What's in it

• **6 Jaegers you can pilot:** Gipsy Danger, Striker Eureka, Crimson Typhoon, Cherno Alpha, Coyote Tango and Horizon Brave, each with its own weapon and signature move
• **8 Kaiju from Category I to V:** Karloff, Spineback, Knifehead, Leatherback, Otachi, Raiju, Scunner and Slattern
• **Kaiju attacks:** they come in from the sea (or burrow up inland), with sirens, a warning before they surface and the weather turning on you
• **Kaiju Blue:** toxic blood that spreads across the ground as a liquid. You'll want the hazmat suit.
• **Carcasses** that you butcher for the parts the better Jaegers need
• **Base and travel:** Jumphawk airdrops, Jaeger Bays and abandoned Shatterdomes on the coast
• **Villages** that ring their bells when something is coming
• **An endgame:** find the Breach and seal it
• **Its own soundtrack** for alerts, fights and Jaeger drops

Getting started

You start with a **LOCCENT Field Manual**. It covers most of this page in game, so hang on to it.

Nothing attacks for the first three in-game days, so use them. Jaegers are expensive. You'll need plenty of iron and copper, plus redstone, gold, diamonds, amethyst, a water bucket and a lava bucket.

If you want a head start, go looking for a **Shatterdome**. They're big concrete hangars on the coast, and about half of them still have a damaged Mark I Jaeger parked inside. The Jaeger Bays in there will fix it up for you. Sneak and right click with a **Kaiju Scanner** to get the direction of the nearest one.

Building your first Jaeger

The first Jaegers you can build are **Cherno Alpha** and **Coyote Tango**. They don't need any Kaiju parts.

1. Craft the parts: Hull Plating, Hydraulic Actuators, Control Circuits, a Neural Interface, a Conn-Pod and a Nuclear Vortex Turbine.
2. Put them together into a **Jaeger Core**.
3. Right click the core on open ground. The Jaeger builds itself from the feet up.
4. Right click the Jaeger to climb in.

If you'd rather have it delivered, **sneak and right click** the core under open sky. Four Jumphawks will bring it in on cables.

To put a Jaeger away, get out, sneak and right click it with an empty hand. It packs back into its core, with its damage and upgrades kept.

In creative, the core is how you spawn a Jaeger, and it isn't used up. Kaiju have spawn eggs. Both come out at the size set in the config.

Piloting

Key	What it does
W A S D	Walk. Hold sprint for full stride
Left click	Punch combo: left, right, uppercut
Right click	Main weapon
R	Ground slam
G	Signature move
B	Second signature move (Gipsy's Chain Sword)
Space	Thrusters
Z	Brace. Tap it just before a hit lands to parry. Mash it to break free when a Kaiju has you pinned
H	Horn
V	Camera distance

Everything uses reactor energy. The HUD shows hull, reactor and speed on the left, and your moves and their cooldowns on the right. A red key means you're short on energy.

Jaegers are heavy. They take a few strides to get going and to stop, turn slowly, and build up speed the longer you keep going. Every punch takes a moment to wind up and lands like a wrecking ball. At a run you'll go straight through houses, and your punches dig into hillsides.

You can't be hurt while you're inside. If your Jaeger goes down you get thrown clear, and then you should keep running, because the reactor blows a few seconds later.

The Jaegers

Jaeger	Mark	Weapon	Signature
Cherno Alpha	I	Incinerator, which sets the ground on fire	Tesla Fist, with lightning	Toughest and slowest. Analog, so EMPs don't stop it
Coyote Tango	I	Arc Cannons	Ion Cannon, a beam that cuts a trench	Best at range
Horizon Brave	I	Harpoon Chain, which reels Kaiju in	Drill Fists	Drags Kaiju in close
Gipsy Danger	III	Plasma Caster	Elbow Rocket, Chain Sword	Analog, so EMPs don't stop it
Crimson Typhoon	IV	Plasma Repeaters	Thundercloud	Three arms, very quick
Striker Eureka	V	Missile Salvo	Sting Blades	Fastest of them all

The Kaiju

Kaiju	Category	Watch out for	How it defends
Karloff	I	Ramming and tail swipes	Crosses its forearms over its skull
Spineback	II	A volley of quills from range, and a rolling charge	Turns its quills into your fist, which hurts
Knifehead	III	Goring charges with its head blade, and ambushes from the shallows	Shields itself with its head blade, then stabs back
Leatherback	IV	An EMP that shuts down every Jaeger except Gipsy and Cherno, then a pounce that pins you	Crosses its huge forearms
Otachi	IV	Acid. Once it's hurt it takes to the air, and it can carry a Jaeger up and drop it	Leaps back on its wings
Raiju	IV	Very fast. Its three-way jaw latches on	Darts aside and bites from the flank
Scunner	IV	Armoured front, so hit it from the sides. It pins you down and pounds	Hunches under its armour, horns lowered
Slattern	V	104 blocks tall, on all fours. Neck strikes, a storm of tails, a mouth beam and a throat lift. It calls for help when it's losing	Takes it on its crowned skull

Heavy hits build up **stagger**. A staggered Kaiju wobbles and takes extra damage, so that's when to unload everything. Once it's back on its feet it can't be knocked down again straight away. Badly hurt Kaiju become **enraged** and hit harder.

Every Kaiju has its own **combos**, two or three blows one after another. Each blow gets a parry cue, and parrying any of them breaks the chain.

Kaiju also **defend themselves** from punches they see coming. A guard soaks up most of a punch and gives way after two or three, so finish your combo with the uppercut. A **ground slam smashes it at once**, and weapons go straight past it. Raiju and Otachi dodge instead. After a block or a dodge, a Kaiju may hit straight back, so be ready to parry.

You can fight one on foot if you're brave. Normal weapons only do about 40% damage.

Alerts

About a minute before a Kaiju surfaces, you get a **KAIJU ALERT** telling you its category, the direction and how far out it is. The HUD counts down to landfall. Build **Warning Sirens** around your base. They wail during alerts and give off a redstone signal.

Kaiju come in from the sea and head for land. They go after piloted Jaegers first, then players, golems and villagers, and they flatten whatever's in the way. Far from the sea they burrow up out of the ground instead. If nobody goes near one for 4 minutes, it heads back to the Breach.

Later on you'll get Double Events. Eventually a Category V turns up with two Category IVs as escorts.

The **Kaiju Scanner** tells you what's out there, how far away it is and how much health it has left. With nothing around, it predicts the next attack.

After the fight

Kaiju drop hide, bone, teeth and Kaiju Blue when they die. The bigger ones often drop a **Kaiju Brain Fragment** as well.

The body stays for 40 minutes, and you can keep harvesting it:

• Axe or sword: hide, and now and then a brain fragment from Category IV and up
• Pickaxe: bone and teeth
• Glass bottle: Kaiju Blue

**Kaiju Blue is toxic.** It pours out of wounds and bodies, spreads, kills plants and poisons anyone standing in it. Each hazmat piece blocks a quarter of the poison, so wear all four. You can bottle it straight from the pools.

These parts go into the later Jaegers (Gipsy, Crimson, Horizon and Striker) and into upgrades.

Upgrades and repairs

There are five upgrades: armour, fists, reactor, servos and weapons. Each goes up to level 3. Right click your Jaeger with one to install it.

A repair kit restores 120 hull and an iron block restores 25. A **Jaeger Bay** loaded with hull plating repairs and recharges any parked Jaeger nearby while you're out of it.

The Breach

This is how you win.

1. Get a Kaiju Brain Fragment.
2. Craft a **Drift Rig** and use it with the fragment in your inventory. You'll see where the Breach is. It sees you too, and the next attack comes early.
3. Head there. It's on the sea floor, so bring night vision and water breathing. The rift opens up once you get close, and **it's guarded**: Kaiju climb out of the rift and keep watch over it, and they go for anything that gets close. Kill them and the way is open for a while, but the Breach replaces them after a day. The more attacks you've survived, the more guards there are.
4. Craft a **Breach Charge** and use it inside the rift. You can also hold it in your Jaeger's hand.
5. Another Kaiju climbs out to stop you, and every guard still alive comes for you. Hold them off and get clear before the 30 seconds run out.

After that, attacks get rare and a lot weaker.

Roadmap

This is the plan, not a promise. The order can change, and the comments shape it.

**Next: polish and balance (1.4.x)**

• Tune fight length and damage for every giant matchup, so Category IV and V fights feel like boss fights without dragging on
• Give each Jaeger its own giant animations for its weapons and signature moves. Gipsy has hers; the rest are next
• More dismemberment, plus Gipsy's power-up, EMP shutdown and death at giant size
• Better performance in big fights, and fixes for the model details players have spotted

**Progression**

• A proper climb from Mark I to Mark V: research Kaiju samples at a Shatterdome to unlock the later Jaegers, instead of just crafting them
• Fallen Jaegers out in the world that you can salvage for parts
• Swap weapons and parts on your Jaeger at a Jaeger Bay

**New Jaegers**

• The first film's other Jaegers first: Tacit Ronin, Romeo Blue, Brawler Yukon and Echo Saber
• Then more from the lore

**New Kaiju**

• More film Kaiju
• A rogue Jaeger boss

**The Breach update**

• A Breach closer to the film: a deeper rift and Kaiju coming through it in waves
• Category V guards once you've survived enough attacks
• Sealing it the film's way, by carrying a nuclear payload through

**Later, maybe**

• Two pilots in one Jaeger. It's the most requested feature, but it's hard to do well, so it won't be soon
• Kaiju fighting other mods' monsters
• A better first-person view from the conn-pod

All the items

Everything's in its own creative tab, if you'd rather look around first.

Config and commands

Everything is configured in config/rim.json, including body size, attack timing, damage, destruction, Kaiju Blue, screen shake, music volume and HUD size. Edit it and run /rim config reload.

Ops get /rim commands for testing, for example:

• /rim kaiju spawn knifehead offshore
• /rim jaeger gipsy_danger
• /rim breach trigger 3

Notes

• It works with Sodium and Iris. The screenshots use the Nostalgia shader by RRe36, which isn't included.
• Giant fights throw a lot of particles. If your game struggles, lower effectsIntensity in the config or set Particles to Decreased.
• Fan-made. Not affiliated with Legendary Pictures or Warner Bros.
