The base range comes from the direction of the port, such as PC to mobile or mobile to console. iOS and Android together count as one mobile target, 20% above a single store, and each console is a target of its own. The most expensive target counts in full and each other target adds 70% of its own route. The multipliers apply to the whole range, then platform services and certification are added as fixed amounts. The timeline is the cost as time for two senior engineers at £500/day each, plus the platform holder's review on console.

This estimate is a planning guide, not a quote. Costs may increase or decrease after reviewing your codebase, assets and target platforms, or as your feedback and requested changes affect the scope. We confirm the scope and pricing basis before work starts and agree any later changes with you before carrying them out.

What Affects Porting Cost?

Source Engine

Unity-to-Unity porting (adding a new platform target) is the cheapest. Cross-engine ports are significantly more expensive. Flash rebuilds are essentially new projects with the original game as a reference.

Target Platform

Mobile is generally cheaper than console because there is no certification process. Console adds TRC/TCR compliance testing, devkit costs, and potentially longer QA cycles.

Input and UI

A game designed for mouse and keyboard needs significant UI adaptation for touch screens. A touch game going to console needs controller mapping and HUD rethinking.

Multiplayer Complexity

Single-player games are straightforward. Server-authoritative multiplayer requires infrastructure changes, matchmaking adaptation, and cross-platform play decisions.

Codebase Quality

A clean, modular codebase is faster to port. Tightly-coupled or undocumented code requires more time to understand, adapt, and test.

Frequently Asked Questions

In our estimator a Unity game going from mobile to PC with little UI work takes 2 to 5 weeks. A PC game in stylised 3D going to iOS and Android with its UI resized takes 6 to 15 weeks. A PC game going to one console with first-time certification takes 12 to 25 weeks, including 4 to 8 weeks of platform review.
We specialise in Unity. If your game is already in Unity, porting to a new platform is straightforward. If your game is in another engine, we would typically rebuild key systems in Unity rather than doing a direct port. This is more of a rebuild than a port.
Yes. Our App Store Launch service covers submission, compliance, and store listing optimisation. Learn more →
Flash games cannot be "ported" in the traditional sense. They need to be rebuilt in a modern engine. We rebuild Flash games in Unity or HTML5. Legacy Modernisation →
We can implement cross-platform play for multiplayer games. This adds engineering complexity for account linking, matchmaking across platforms, and platform holder requirements. The cost estimate accounts for this if you select multiplayer features.
