What you lose while your game remains on CryEngine?

While your game remains on CryEngine, competitors are not standing still: modern players expect frequent updates, smooth gameplay, and support for new devices.

An outdated engine requires more and more time to adapt with each update, and players leave for projects that launch instantly and run without glitches.

But the main problem goes deeper — technical debt. The longer a game lives on CryEngine, the more expensive every change becomes: new content, bug fixes, patch releases.

Developers spend resources fighting engine limitations instead of improving gameplay mechanics and delighting the audience. In the end, you pay twice — for maintaining the old architecture and for missed opportunities.

Against this backdrop, competition suffers too. While you invest effort in maintaining old code, rivals on modern engines ship updates several times faster, enter new platforms, and capture the attention of your own audience. Players don't dig into technical reasons — they simply choose the game where they feel comfortable.

We help break this cycle. Porting your game to Unity removes the limitations of the old engine: you get a modern infrastructure, development flexibility, and the ability to respond quickly to market demands.

Content that used to take months starts shipping in weeks, and players return to a project that is evolving.

Rethinking your strategy now is not about costs, but about preserving your audience and market position. As long as the game remains on CryEngine, every day means lost players and market share given to competitors.

Shall we talk about how to migrate your project to Unity without losing quality and with minimal risks?

What benefits you get from porting to Unity

Moving a game from CryEngine to Unity is not just a technical change. It is a management decision that directly affects audience reach, operational costs, and the long-term sustainability of the project. Let's look at the main benefits you get as a product owner.

Audience growth

Unity opens access to a huge ecosystem of platforms — from PC to mobile devices, consoles, and web versions. The game is no longer tied to one device category and goes where players spend the most time. Every new platform means new users that were previously out of reach.

Cost reduction

A single Unity project instead of several separate versions for different platforms reduces development and update preparation costs. You spend less time on duplicating content and routine operations, and the team ships fixes and new features faster. In the long run, this is significant budget savings.

Cross-platform compatibility

Modern players expect the game to be available on their favorite device. Cross-platform compatibility allows starting a session on a computer and continuing on a smartphone while keeping progress.

Convenience improves player retention and increases the number of positive reviews — and that is additional organic marketing.

Stability

Unity is a mature platform with regular updates and a huge developer community. This reduces the number of technical failures and bugs that drive players away. Fewer problems means less spending on emergency tech support and greater trust in your product.

Porting to Unity is a strategic investment in the future of the project. You get not just a “game migration,” but a tool for market expansion, process optimization, and strengthening brand reputation.

Porting formats from CryEngine for your task

Your game already runs on CryEngine, but development is hitting engine limitations: it's hard to launch a mobile version, hire the right specialists, or speed up update releases.

Porting to Unity preserves game logic, player progress, and monetization — while removing technological barriers and opening new platforms, from PC to smartphones.

We offer three cooperation formats — you choose the depth of involvement in the project. In every case, you get a working result, not a “promise that we will migrate it someday.”

Format For whom What the client gets
Full migration The project needs a complete switch to Unity: changing the platform, releasing a mobile version, abandoning the old technology A ready game on the new engine with the same gameplay, preserved player data, and configured monetization
Partial migration Need to migrate individual blocks: interface, characters, scenes, or service integrations Targeted changes without stopping the project: we migrate only what hinders development, the rest works as before
Consulting The team plans to handle the migration itself but needs expert backup A clear action plan, architectural decisions, and priorities — you avoid typical mistakes and save time

Work under any format follows a transparent scenario: audit of the current code, migration plan, phased deliveries, and tests at every step. You see the first results within a couple of weeks, not at the end of the project. All that remains is to accept the finished version and bring it to new platforms.

How a porting project goes: from brief to launch

We migrate games from CryEngine to Unity while preserving mechanics and the players' experience. Each development stage is transparent: you know what is happening and can always step in. This approach eliminates unpleasant surprises at the finish.

  1. Brief. You tell us about the project: target platforms, players, and features that must be preserved. We ask questions to understand the product as well as you do.
  2. Audit of the source project. We evaluate the codebase, assets, and dependencies. We come back with a clear report: scope of work, risks, preliminary timeline.
  3. Plan and approval. We fix the stages, timeline, and cost. We prioritize tasks and discuss trade-offs. Once you approve, we finalize the document and start.
  4. Implementation. We migrate game mechanics, interfaces, saves, and purchases. You control the process through demo versions without diving into technical details.
  5. Intermediate demos. We show progress after each major stage. You provide feedback — we make corrections right away.
  6. Testing. We check stability and compatibility on target devices. We fix anything that could affect player experience.
  7. Launch and support. We help release the game, analyze initial feedback, and ship updates. We stay nearby after release.

As a result, you get a predictable project: the game is ported on time, with clear costs and minimal risks.

What is included in the delivery after porting is complete

After porting is complete, you get not just a working game, but a complete package that makes the project transparent and manageable.

All the work migrated from CryEngine is carefully packaged and handed over to you — without hidden details or contractor “magic.” This is a guarantee that you control the product, understand how it works, and can develop it with any team.

The delivery includes:

  • Unity source code — the entire migrated project is stored in your repository. The code is fully yours, so you don't depend on specific developers and can bring in any studio to continue development.
  • Technical documentation — project structure, mechanics descriptions, environment settings, and build order. A new team can get up to speed in days, not months, and start making changes immediately.
  • Automation scripts — ready-made build and deployment procedures for all target platforms. Releasing updates becomes a few clicks and takes minutes, not hours of manual work.
  • Final game builds — versions built for the platforms you need. They can be sent immediately to stores, testers, or partners for demonstration.
  • Training for your team — we conduct onboarding for developers and the lead specialist: we explain how the migrated project is structured, where to find the required elements, and how to make edits without risking breaking anything.
  • Support after delivery — during the warranty period, we fix bugs related to the migration of logic and data. This is your insurance against unexpected issues in the first weeks of operation.

This package addresses the client's main fear — dependence on the contractor. You get clear code, a trained team, and full control over the product.

Case study: audience growth and cost reduction after porting

Porting from CryEngine to Unity solved the studio's main problem: the game was available only to owners of powerful computers, so up to 60% of potential players went to competitors. Supporting a narrow platform ate the budget, and every new build required lengthy optimization.

We completed the move in three months and set up automated update publishing in parallel — updates now ship several times faster, and the team isn't distracted from developing new features.

What changed after porting

For Vector Games, the result was a turning point: the audience grew 2.5 times in the first quarter, and technical support costs dropped by 40%.

The game began running stably on mid-range laptops, and thanks to this, we entered a new platform with less powerful devices without extra effort.

The average number of concurrent players tripled, and the share of repeat in-game purchases increased by 20%. The team stopped spending resources on endless optimization — instead, they focused on new content that attracts even more players.

We continue to manage the project now: we release updates and expand functionality. The porting paid for itself in five months, and it became a growth point for the studio — player retention remains high, and the audience regularly receives fresh content.

Why this is your case

If your game is also limited by a technical platform, or you spend too much on support, porting solves both problems. You get more players, lower costs, and a team that continues to develop the project after the migration.

Frequently asked questions from clients about game porting

Moving from one platform to another is a responsible step, and clients naturally have questions about safety, timelines, and preserving game quality. We answer the most common ones so that you can make a decision without hidden risks.

How safe is porting for the source code and data?

Full preservation of your code and game assets is our responsibility. We work under an NDA agreement, use private repositories, and deliver the result only to you. The source code is not shared with third parties, and all intermediate versions are stored on secure servers.

How long does porting a game take?

Timelines depend on the game's size and the complexity of its logic. For a typical medium-sized project, porting takes 4–8 weeks. After the brief, you receive an accurate calendar plan with stages and milestones — you always know what stage the work is at.

Will the game quality suffer after the move to Unity?

We migrate not only mechanics but also graphics, physics, and optimization for target platforms. After porting, a testing cycle is carried out: scenarios, performance, and compatibility are checked. You get a game that works as stably as the original, and even faster on some devices.

What happens after the work is completed? Do you provide support?

We don't abandon the project after handing over the code. For one month after launch, we fix bugs that may appear on real devices free of charge and consult your team. After that, you can take out extended support — we will update the game for new system versions and add changes.

If you still have questions, ask them at a free consultation. We will answer regarding your project and propose an optimal porting plan with fixed cost and timeline.

Let's discuss moving your project to Unity?

Moving to Unity is not a technical migration but a strategic decision that affects the speed of updates, game stability, and the budget for its support.

A well-planned migration reduces expenses in the long run and opens new opportunities for the project's development, so the first step is a conversation about your goals, not about code.

We have worked with projects of various sizes and know how to migrate a game without stopping online operations, losing players, or losing accumulated progress.

Fill out the request form, and after the first consultation you will get a clear picture: what the migration costs, what risks exist, and how long the process will take.

What you get after contacting us

  • a personal consultation with our technical manager — we will review your tasks, goals, and constraints;
  • a cost estimate in two versions — “minimum” and “budget-optimal” — so you can choose according to your plans;
  • phased work planning: from migrating logic to setting up payment systems and analytics;
  • an assessment of player progress preservation and compatibility with current platforms;
  • specific deadlines and a list of responsible people so your team understands its tasks.

Leave a request for a consultation — within one business day we will send a cost estimate and suggest a time to meet. This is not binding, but you will get an accurate transition plan and be able to make an informed decision.

How to choose the right porting format for your task?

The right porting format is determined not by fashion, but by your task, deadlines, and budget. One thing is to migrate a project from CryEngine to Unity in order to reach new platforms and expand the audience. Another is to preserve functionality and update the interface without increasing support costs.

How to choose? Start with your commercial goal. If the priority is a quick launch on a new platform, a full “turnkey” port is suitable: we take on the migration, testing, and release.

If you want to save money and fit a limited budget, adapting key modules and phased migration are enough — you get a working product and pay only for the required scope.

The format also depends on your team. When you have in-house developers who need expertise, we work in a consulting and support mode. When there is no team, it is wiser to entrust the project to us — you don't keep a staff of specialists for one task and get a guaranteed result. In both cases, you pay for the result, not for extra resources.

We help you with both the choice and the planning: we assess the project, give realistic timelines, and suggest the optimal format. We fix the task, scope, and budget before the start — this eliminates overpayments and unexpected surprises. This way, you get a clear route and confidence at every stage.

The main thing is not to choose a format blindly. Tell us about your task — we will offer a solution that matches your goals, timeline, and budget.
