Game Porting Services

Game Porting Services

PC and console to mobile, mobile to PC and Steam, and engine-to-Unity rebuilds. From the London studio whose principal engineer led the RuneScape Mobile port at Jagex.

Game porting from the team behind RuneScape Mobile

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 led 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

£500 per 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 a London studio

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

What working with a London studio gets you

  • London-registered and Shoreditch-based, with in-person kickoffs and milestone reviews. 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

Fixed price

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

£500/day per developer

Milestone billing with weekly playable builds. £900/day for a paired engagement.

Start with the audit

A fixed-price feasibility audit gives you a written verdict: what your port costs, how long it takes, and whether it's worth doing at all. If the answer is don't bother, we'll say so, with reasoning in writing.
