How Game Co-Development Works, Step by Step

How game co-development works in practice: NDA first, a fixed-price first milestone, shared tools, client-owned IP and support after launch.

What co-development means

Game co-development is when an outside studio builds part of your game alongside your own team. You keep creative direction and ownership. The partner takes on a defined slice of the work: a feature, a platform port, a content pipeline, a vertical slice, or extra engineers who join your sprints.

It sits between two other models. Full outsourcing hands a whole project to another studio. Staff augmentation adds individual people to your team. Co-development can use either, but the defining trait is shared ownership of the result: both teams work in the same repository, the same task tracker and the same build pipeline.

When it makes sense

Co-development is a good fit when:

Your team knows what the game should be but does not have enough hands to hit the next milestone.
You need a skill you do not have in-house, such as multiplayer networking, XR, performance optimisation or console ports.
You want to prove a risky idea with a prototype before committing a full team to it.
You are shipping and need people to keep patches, platform updates and ports moving after launch.

It is a poor fit when nobody on your side can review the work, or when the scope changes every week with no one deciding priorities.

How an engagement runs

1. NDA first

Before you share a pitch deck, a design document or a build, both sides sign an NDA. At Feative Studios we sign the NDA before we ask for any project details.

2. Scope call and written brief

A short call covers the goal, engine, platforms, team size and deadline. We then send a written brief that lists what is in scope, what is out of scope and how each piece will be accepted. We reply to briefs within 24 hours.

3. A small fixed-price first milestone

Instead of signing up for months of work, you can start with one small milestone at a fixed price: a prototype, a vertical slice, or one feature built to production quality. It shows you how the partner writes code, communicates and handles feedback, at a cost you already know. If it works, you scale up. If it does not, you stop.

4. Shared tools from day one

Co-development only works when both teams see the same truth. In practice that means:

One source of truth for code and assets (Git LFS or Perforce, whichever you already use)
One task tracker, with the partner's tickets in your board
Builds produced by the same pipeline, so nobody argues about "works on my machine"
A named point of contact on each side

We work in Unreal Engine, Unity and Godot, and match your existing tools when we can.

5. Milestones or embedded developers

After the first milestone there are two common ways to continue:

Fixed-price milestones: each milestone has a scope, acceptance criteria and a price agreed up front. Good when the work can be described clearly.
Embedded developers on a monthly retainer: engineers or artists join your sprints and take tasks from your backlog. Good when priorities move often.

Many teams mix both: a fixed-price milestone for a well-defined feature, plus embedded developers for day-to-day production.

6. Launch and after

Shipping is not the end of the work. On the monthly retainer, the same people who built the feature can stay on for patches, platform updates and ports, so knowledge does not leave with the contract.

Who owns the IP

You do. Code, art and assets created for your project belong to you, 100%. That should be written into the contract before work starts, not settled at the end.

How fast you can start

Once scope is agreed, a co-development team can usually start within 3 to 7 business days. The slowest part is rarely hiring; it is access: repository permissions, build machines, accounts on your tracker. Sorting those during the scope stage saves the first week.

What to ask a co-development partner

Will you sign an NDA before we share details?
Can we start with a small fixed-price milestone?
Who owns the code and assets, and where does the contract say so?
Will you work in our repository and tracker, or your own?
Who is our day-to-day contact?
What happens after launch?

If a partner hesitates on any of these, that tells you something.
