R.E.P.O. Beginner Guide: Stop Grabbing Loot and Start Running a Removal Crew (Haul + Unity Physics Tech Explained)

Stop treating R.E.P.O. like a looter-shooter. You are not a space marine. You are a mover working for the Retrieve, Extract and Profit Operation, and the sofa charges you when you bang it through a doorway.

That is the whole beginner shift in one sentence: run a removal crew, not a grab run — cart first, two hands on heavy glass, extract in batches, spend SURPLUS on stamina before guns. Do that and your first three quotas stop feeling like chaos and start feeling like plumbing.

This guide covers the Early Access Windows version that launched on Steam on 26 February 2025, for 1–6 players, through the current 4-level, 29-enemy build — plus why Unity PhysX and Photon PUN explain the wobble and the lag. The Nintendo Switch 2 port listed for 2027 is out of scope here.

What R.E.P.O. actually asks you to do

R.E.P.O. is an online co-operative survival horror game developed and published by Swedish studio Semiwork for Windows, released in early access on 26 February 2025 on Steam, and developed in the Unity game engine. The name expands to Retrieve, Extract and Profit Operation.

The loop is deliberately close to Lethal Company, but with physics as the joke and the threat:

• Host up to six players and hunt for valuables and funny objects across randomized modular maps with different room layouts, item placement and enemy distribution.
• Handle objects carefully and avoid breaking or damaging them, which lowers their value, while bringing them to extraction points to receive in-game money called SURPLUS.
• While you loot, hostile monsters try to kill you.
• On each level you must fill each quota at each extraction point before escaping to the truck. You are incentivized to haul extra valuables to spend more, but you risk the transport itself and every extra enemy interaction.
• Between levels you visit a Service Station to spend SURPLUS on permanent upgrades, weapons, explosives, tools, and resources like health and energy for those weapons and tools.
• At its core the game prioritizes verbal cooperation, coordination and strategic planning.

The Early Access FAQ on Steam says the current state is 4 levels, 29 enemies, plus many items, weapons and upgrades, with about a year and a half of early access planned and more customization, meta progression, story, upgrades, equipment, levels and enemies promised for 1.0.

Why should you trust that this moving-company framing is not just flavor? Look at the launch numbers. R.E.P.O. hit a peak of 230,000 concurrent players in its first weekend, was the highest-grossing paid game on Steam for 11–18 March 2025 and second in overall revenue behind Counter-Strike 2, held 145,000 active players on 11 March 2025, holds an overwhelmingly positive Steam rating as of January 2026, won Best Early Access Game at the Golden Joystick awards on 20 November 2025, and even put its Semibots into Fortnite: Battle Royale as a Fortnitemares outfit on 25 October 2025. A $8 physics courier game does not do that unless the haul is the game.

The 6 rules that fix most failed runs

1. The cart is your sixth player

If you play without the cart you are playing hard mode. Roll it to the loot, load low and centered, push — do not drag — through doors. One player drives while another walks ahead opening doors and checking corners. The cart absorbs the little bumps that would otherwise shave value off every plate.

Think of the dock runs in Adventure Miner: you do not fill the backpack to 100% every time if an early return buys capacity sooner. Same here. A half-full safe extraction beats a full cart lost to a clown beam.

2. Two hands on anything tall, round, or glowing

Solo lift is for mugs and books. Anything statue-sized, vase-shaped, or over your head needs two carriers. Lift together, walk slow, count doorways out loud. Most value loss I see is not monsters — it is one player sprinting a grandfather clock sideways into a frame.

This is not caution theater. It is mass.

3. Extract in batches, then get greedy — in that order

Quota first, greed second. Fill the extraction point to quota, trigger it, then keep scavenging with the truck as your exit already secured. New crews do the opposite: they stack the perfect $12,000 pile next to the extractor while quota sits at 60%, then a Banger pack walks in.

Service Station logic follows the same order: buy survivability before firepower. Health, energy, stamina and cart-adjacent upgrades keep every future haul alive. Guns feel good and solve one monster; stamina solves every doorway.

4. Noise kills more beginners than monsters do

Crouch, whisper, hide. R.E.P.O. is a verbal game — Photon Voice quality is explicitly called out by the developers as central to fun moments because voice is clear and not too delayed — which means your microphone is also a monster lure. Plan who talks, when, and who stays mute on watch.

A good low-stakes place to rehearse this is 911: Prey. That browser horror escape is all about staying quiet, covering tracks, timing moves between camera sweeps, and using the environment to hide. If you can cross its maniac house without sprinting, you can cross R.E.P.O.’s second extraction without shouting over a Huntsman.

5. Learn four monsters, ignore the other 25 at first

You do not need all 29 monsters memorized. IGN’s monster list currently tracks all 29 with health and damage, and four patterns cover most early wipes:

• Gnome — HP 20, Attack 10. Annoying alone, run-ending in groups because they deliberately target valuables to destroy their price and swarm you while you hide from bigger threats. Counter: just lift and smash them. Do not walk past them to save time.
• Apex Predator duck — HP 150, Attack 10. Cute duck follows you, jumps in front of you, begs to be clicked. Click and it turns monstrous and flies at you. Counter: slow down, look away, do not touch.
• Banger — HP 50, Attack 30 plus knockback. Lit dynamite skulls that explode up close and love packs. One is survivable; three is lights out. Counter: distance, never melee a pack.
• Clown — HP 250, Attack 100. Produces a beam that is a one-hit kill without health upgrades. You must read high vs low and jump or duck accordingly, plus respect the little kick. Counter: identify the height early, move once and commit.

Two more worth knowing when you stop dying to the first four: Animal (HP 150, Attack 2) is weak but throws everything around if set off near your cart, and Cleanup Crew (HP 350, exploding head 75 plus bouncing 10, melee 20–40, radiation 10) is hard to sneak past because multiple heads watch you — aim for the body.

6. Solo is a different job than 6-player

Solo means you are driver, lifter, lookout and bait. Take smaller items, use the cart as a wall, extract early and often. In 5–6 player chaos, assign roles: two haulers, one cart driver, one scout, one or two floaters who handle Gnomes and watch rear. The game scales bodies, not door width — more hands help only if fewer people talk at once.

Why everything wobbles: Unity PhysX in plain English

R.E.P.O. began as a single-player cleaning horror prototype while Semiwork explored Unity, then pivoted to multiplayer because teamwork felt fun. Unity itself is the world’s leading game engine for building and deploying across desktop, iOS, Android, Nintendo Switch, PlayStation, Xbox, Meta Quest, web and more, letting small teams prototype in C# for 2D and 3D and ship to over 25 platforms. Unity’s own creator list now names R.E.P.O. by semiwork alongside PEAK, Schedule 1, Cult of the Lamb and Silksong.

Under the hood, Unity’s default built-in 3D physics is an integration of the Nvidia PhysX engine for object-oriented 3D projects. That sentence explains half your clips:

• Rigidbody gives objects movement, gravity and collision. In Unity you configure that with the Rigidbody class and component. Mass, drag, and whether the body sleeps matter. A dinosaur statue is not a sprite — it is a mass with velocity.
• Colliders decide what counts as a hit. You must configure colliders so the system can accurately detect collisions. Every doorframe, cart edge and teammate is a collider. Squeeze too fast and the solver bills you.
• Joints and articulations connect bodies. Joints connect GameObjects and simulate pivoting, movement and restriction; articulations handle complex chains of rigid bodies. Two-player carries are effectively a human joint — which is why desynced walking twists the load.
• Interpolation smooths jitter, sleeping saves performance. Unity can interpolate Rigidbody movement that looks jittery and put sleeping bodies to rest to save CPU. When a vase vibrates on the cart then suddenly launches, you are seeing interpolation and wake thresholds lose an argument.

So the rule “slow is fast” is literal: low relative velocity means low solver energy, fewer collision callbacks, less value damage. Sprinting a fragile haul is asking PhysX to resolve a high-speed joint impact in a doorway built for one bot.

Why co-op feels drunk: Photon PUN in plain English

If Unity explains the wobble, Photon explains the ghost wobble — the version where your friend sees the vase two meters left of where you see it.

Semiwork had no prior multiplayer experience and chose Photon PUN on the recommendation of fellow developers Landfall of Content Warning as a fun and sturdy way to do multiplayer. PUN was quick to set up and easy to work with, and quick playtests right in the editor saved a lot of time. Photon’s dashboard made it easy to add hosting regions after launch to keep latency decent, and Photon Voice gave clear, low-delay audio that even lets the game animate the little Semibot faces to the audio.

But PUN does not provide much for multiplayer physics out of the box. Semiwork said making all the physics feel smooth for clients was something they struggled with for a long time, and only lots of custom work made it fun. The Photon team’s own write-up lists why: network latency, inconsistent frame rates, non-deterministic physics engines, bandwidth limits and authority conflicts. Physics engines are not perfectly predictable across machines, objects drift if not synced constantly, and syncing constantly is too bandwidth-heavy. Players see lag as visual desyncs; different hardware calculates slightly different results.

That is why R.E.P.O. scaled the way it did — around 8.7 million sold copies in March alone per Alinea Analytics, scaling from zero to hundreds of thousands of concurrent users with DDoS protection and custom server plugins — and still feels host-bound on bad routes. When the host stutters, everyone’s furniture stutters. When a client grabs a heavy object, authority has to decide who owns that Rigidbody now.

Practical takeaways:

• Let the most stable connection host, not the loudest friend.
• One owner per heavy object. Do not tug-of-war a statue — hand it off.
• If the cart jitters, stop. Waiting one second for authority to settle is cheaper than re-collecting $4,000 in shards.
• Keep voice short. Voice drives both coordination and monster aggro, and Photon Voice clarity cuts both ways.

Photon now recommends Fusion or Quantum for new physics-heavy games — Fusion and Quantum handle modern deterministic sync better — but R.E.P.O. shipped weeks after the team heard about it, so changing SDKs was not an option. You are playing a PUN game polished by brute force. Respect that and you will forgive the occasional flying chair.

My take: the Mover’s Tax (and why I disagree with “guns first”)

Most quick-tip lists tell beginners to rush weapons from the Service Station. I think that is backwards, and R.E.P.O.’s design agrees with me.

Call it the Mover’s Tax: every doorway, stair, and extraction slam charges you a small fee in value, health, or time. Guns pay that tax once, against one monster. Stamina, health, energy and carry control pay it down on every haul. A team with upgraded legs and a calm cart driver extracts more SURPLUS over five levels than a team with a shotgun and no discipline, because the second team still pays full Mover’s Tax on every corner.

Related idea: Porcelain Paranoia beats speed. Lethal Company rewards sprinting the loot back. R.E.P.O. punishes it because value is fragile and shared. The fastest crew I have watched was also the poorest — they arrived first with 40% value. The richest crew looked boring: crouched, quiet, two on the piano, one on the door.

Third, the cart is not storage, it is a teammate. Park it as cover against Huntsman line-of-sight, as a Gnome trap, as a doorstop while you scout. If you treat it as a wheelbarrow you will abandon it when chased. If you treat it as the sixth bot, you will bring it home.

I cannot prove these with frame-perfect numbers — Semiwork does not publish value-decay formulas or per-item mass, and I did not run instrumented tests. Open questions I would love answered: What is the exact damage curve for impact speed vs value? Does two-person carry halve damage or just stabilize velocity? How does PUN authority transfer interact with heavy-mass thresholds? Until those are public, take the Mover’s Tax as a useful lens, not a law.

If you want a mental drill for the economy side, play a few rounds of Backpack Idle. It is an idle game about putting items into backpack slots to maximize earnings, organizing gear to earn passive income, unlocking through research and prestiging to improve. No monsters, just value-per-slot thinking. That is exactly the Service Station mindset: pack tight, upgrade the container before the gun.

Browser drills while your crew is offline

• For noise discipline: 911: Prey — sneak, cover tracks, time escapes. If you trigger the maniac by sprinting, you will trigger a Reaper by shouting.
• For packing discipline: Backpack Idle — maximize earnings per slot, prestige deliberately. Good stand-in for cart Tetris and Service Station spending.
• For route discipline: Adventure Miner — mine, haul to the dock, upgrade capacity first, then power, then speed, and learn dense ore loops. Swap ore for valuables and dock for extractor and you have R.E.P.O.’s economy without the ducks.

None of these replace R.E.P.O. They isolate one tax at a time so your next live run is calmer.

Checklist for your next run

1. Host = best connection, not host = best aim.
2. Cart out first, roles called, mute discipline agreed.
3. Quota batch extracted before greed looting.
4. Heavy/fragile = two carriers, slow through doors.
5. Gnomes smashed on sight, ducks ignored, Bangers given space, Clowns read high/low.
6. Service Station: health/energy/stamina before guns.
7. If physics desyncs, stop moving and let authority settle.

Bring the truck home boring and rich. Leave the highlight clips to the Clown beam.
