The game

A co-op physics heist
on a moving train

You and up to three friends are desert robbers, deep in debt to the syndicate. Your one asset: a clapped-out cargo helicopter.

Every day, loaded freight trains roll past your hideout. Strip enough loot before sunset to pay the day's quota — or the run is over.

How it plays

Everything is physical

No cutscenes, no menus between you and the loot — every robbery is a hands-on scramble on a train doing 60.

01
🚁

Pilot the cargo heli

A fully physics-driven helicopter — your flying crane and getaway ride.

02
🧲

Magnet-haul the loot

Rip pallets and crates off the roof while the train is still moving.

03
🪢

Fast-rope the crew

Lower friends onto a speeding wagon, then pull them back up.

04
🧨

Crack it open

Blow the door, kick out crates and pop locks to reach the sealed cargo.

05
🥾

Handle the guards

Shove, tackle and boot guards off the moving train.

06
🐑

Bend the rules

Drop sheep or a traffic light to stop a train cold.

Co-op: grab loot, sell it, hit the quota or you're done. The same loop we run, in a different setting.

Shared bank, a daily debt quota, and buying sketchy items against a timer — our exact economy, in a casino.

Our edge

The same beloved co-op-loot-to-quota loop these hits are built on — plus a player-piloted cargo helicopter. None of them put a flyable vehicle in players' hands, and none rob moving trains. Familiar fun, a brand-new playground.

The hard part already works

Heli Problems runs today on a mature helicopter sandbox — build v0.85. Physics flight, the magnet crane, modular damage and 1–4 player co-op are all live, and the gameplay trailer is real footage.

The train, robbery and economy systems are coming together on top of that proven base.

Engine: Unity
Netcode: FishNet — a player hosts, no servers needed
Co-op: 1–4 players online
Release: Steam build pipeline ready

Team & the ask

Built by Cave47

Viktor Andreenko
Programmer & Game Director · 7+ yrs

Owns all engineering end-to-end: the physics-driven cargo helicopter, FishNet 1–4 player co-op, gameplay systems (trains, economy, AI, inventory), editor tooling and the Steam build pipeline — a large, working v0.85 build.

The hard engineering is already built and running in the trailer — Heli Problems is now ready for art and design firepower to take it to the finish line.
What we're looking for

A publishing partner to fund two key hires — taking Heli Problems from a proven prototype to a finished, launch-ready co-op hit, with marketing and launch support.
