Game Development · Hoxton, London
RoguePortalGuide is a Hoxton studio crafting roguelikes, procedural worlds, and portal-driven puzzle games — from first prototype to live launch.
The Studio
Founded above a print workshop on Pitfield Street in 2016, RoguePortalGuide is a seven-person studio of designers, engineers, and technical artists. We specialise in run-based games where every session is stitched together on the fly — procedural dungeons, branching portals, and systems that surprise the people who made them.
We ship on PC and console in Unreal Engine 5 and Unity, with an in-house toolchain for procedural generation and playtest telemetry. We take on a maximum of three client projects a year so each one gets a senior team from kickoff to launch — no juniors handed the keys, no offshored crunch.
How we work
Every engagement follows the same spine. We front-load risk with a playable prototype so you never fund a year of work on a hunch.
We pull apart your core loop, define the fantasy, and produce a design pillar doc plus a costed roadmap. From £3,500, credited against production.
A rough but real vertical slice you can hold in your hands. We test the moment-to-moment feel before a single art asset is finalised. From £18,000.
Senior team, two-week sprints, fortnightly builds. Procedural content, systems, UI, and audio integration built against weekly playtests. Day-rate from £520.
Console certification, store setup, patch cadence, and post-launch balancing. We stay on for a minimum three-month tail so launch week is not the finish line.
Capabilities
Hover a card to see the detail. Four disciplines we run end-to-end, in-house, without subcontracting the hard parts.
Wave-function-collapse level design, seeded run generation, and hand-authored set-pieces that read as designed, not random. Our generators ship with a debug seed browser so QA can reproduce any run.
Meta-progression, item synergies, and difficulty curves tuned against real telemetry. We build the economy spreadsheets and the in-engine balancing tools that keep them honest.
Non-Euclidean spaces, recursive rooms, and camera-safe portal rendering in UE5. The tricky maths — seamless traversal, physics hand-off, occlusion — handled so your designers stay in the level editor.
PlayStation, Xbox, and Switch builds prepped, submitted, and shepherded through certification. Input, save systems, and platform storefront requirements sorted before your first submission.
Reviews
A few words from studios and publishers we have built with over the past three years.
The prototype they delivered in five weeks convinced our board to greenlight the full budget. Six months later we shipped to a 91% positive rating. Genuinely the tightest pre-production we have run.
Their portal-rendering work is the real deal — we could not find anyone in the UK who could do seamless non-Euclidean traversal in UE5 until we found Pitfield Street. Worth every pound.
Fortnightly builds, no surprises, and a seed browser that let our QA reproduce every bug. Switch certification passed first submission. That never happens.
We came in with a messy roguelike idea and left discovery with a costed roadmap we actually trusted. They tell you what to cut, which is rarer than it should be.
