Game Porting Services

PC and console to mobile, mobile to PC and Steam, and engine-to-Unity rebuilds. Delivered by senior UK Unity engineers, led by a principal engineer who worked on the RuneScape Mobile port at Jagex.

Game porting informed by RuneScape Mobile experience

Porting is a specialist discipline, not a downscale-and-ship exercise. Input models, memory budgets, thermal limits, and session-length expectations all change between platforms, and teams that treat a port as a rebuild-lite ship something that feels wrong and runs worse. We start every port with a fixed-scope feasibility audit, then give you an honest plan: what it costs, how long it takes, and whether it's worth doing at all.

The three porting directions

We take porting work in three directions. Each one is engineering we have shipped, with named credentials behind it.

PC and console to mobile

Touch UX redesign, not button overlays. Input is where most ports succeed or fail, and a desktop interface dropped onto a touchscreen fails. We redesign the interaction model for touch, manage thermal and memory budgets for sustained sessions on real devices, and test across the Android device spread rather than a single flagship. David was a Technical Developer on the RuneScape Mobile port at Jagex (2017 to 2019): a 20-year-old MMO with a complex desktop UI brought to iOS and Android. Read the RuneScape Mobile case study. At OVG, we picked up Foil Hat Games' live mobile title Nova Blast, modernised its SDKs, and ported it to Android without disrupting their release schedule. Read the Nova Blast case study.

Mobile to PC and Steam

Resolution and aspect-ratio scaling, keyboard, mouse, and controller input, and Steam Deck verification. Steamworks integration covers achievements and cloud saves. We also rework session design for longer desktop play patterns, because a game built around two-minute mobile sessions needs more than a window resize to feel right on PC.

Engine-to-Unity rebuilds

Games in unsupported or commercially dead engines rebuilt in Unity, treating the original as the specification. This overlaps with our Legacy Modernisation service, which covers Flash titles and Unity version upgrades. Either page reaches the same team.

Thinking about console?

We have not shipped a console title, and we won't pretend otherwise. What we do bring is the engineering that console ports stand on: Unity's multi-platform architecture, performance budgets, memory discipline, and the large-scale porting experience behind RuneScape Mobile. If you're weighing a console port, we'll scope it case-by-case and tell you honestly whether we're the right team for it, or point you to a specialist porting house if we're not.

How an engagement works

Three stages. The first is fixed price with a standalone deliverable, and nothing after it happens unless the audit supports it and you agree to proceed.

Feasibility audit (fixed price)

Codebase review, target-platform risk assessment, and a written report with honest cost and timeline ranges and a clear verdict: finish, refactor, or don't bother. The report is yours to keep, whether or not we do the port. Prefer to self-serve first? Run the free Porting Feasibility Checker before any conversation.

Porting plan

A scoped proposal within a week of the audit: milestones, timeline, cost, and the risks we expect to hit. No producer layer. The engineer who scoped your port is the engineer who builds it.

Execution

£600/day ex VAT per developer, milestone billing, and a playable build every week. You see the port running on real hardware throughout, not at the end.

Why work with a UK team

Porting engagements run smoother when you can sit in the same room at the points that matter.

What working with a UK team gets you

London-registered and remote-first, with in-person London kickoffs and milestone reviews available by arrangement. See our London game development page.
UK timezone for EU publishers, with 4 to 5 hours of working overlap with the US East Coast.
The engineer who scoped your port builds it. No producer layer, no handoffs.

What porting costs

Two timeline anchors from real porting work, plus the execution day rate. Day rates are ex VAT.

Feasibility Audit

From £1,500

Fixed price, typically 2 days at our audit rate. Codebase review, target-platform risk assessment, and a written report with cost and timeline ranges and a finish, refactor, or don't-bother verdict.

Mobile-to-PC Port

6 to 8 weeks

A simple mobile-to-PC port with minimal UI changes: desktop input, resolution scaling, and Steamworks integration.

PC-to-Mobile Port

2 to 4 months

A PC-to-mobile port with a touch UX redesign, thermal and memory work, device-tier testing, and store submission.

Execution

£600/day per developer

Milestone billing with weekly playable builds. £1,200/day for a paired engagement.

Frequently Asked Questions

Yes. Non-Unity titles are typically rebuilt in Unity rather than directly ported, treating the original game as the specification. The approach, cost, and timeline differ from a straight port, which is exactly what the feasibility audit establishes. See our Legacy Modernisation service for engine rebuilds and Unity version upgrades.

2 to 4 months for most PC-to-mobile ports, where the touch UX redesign and device-tier optimisation drive the timeline. A simple mobile-to-PC port with minimal UI changes typically takes 6 to 8 weeks. The feasibility audit gives you a range specific to your game.

Yes. Submission, compliance, and the store listing are part of the port, including age ratings, privacy requirements, and managing any review feedback cycles.

We haven't shipped a console title, so we scope console requests case-by-case and answer honestly about fit. The Unity engineering carries over; platform certification experience does not, and we'll say so upfront. If we're not the right team for your console port, we'll point you to a specialist porting house.

We'll tell you, with reasoning in writing. We'd rather lose the work than ship a port that damages your game's reputation. The audit report is yours either way, and you can use it to brief another team or to revisit the port later.

It's implementable. Cross-platform play adds engineering for account linking and matchmaking across platforms, and it's scoped in the feasibility audit so the cost is visible before any work starts.
