How we work
A production path from spark to shipped
Every engagement moves through four disciplined phases. You get playable milestones, transparent budgets, and code you own outright.
- 01
Concept & Pre-Production
from £8,500·4–6 weeksCreative pillars, a one-page design bible, mood and reference boards, and a paper prototype. We de-risk the idea before a line of engine code is written.
- 02
Vertical Slice Prototype
from £18,000·6–10 weeksOne polished, representative slice of gameplay in Unreal 5 or Unity — the moment publishers and playtesters can feel the game. Ideal for pitch decks and funding.
- 03
Full Production & Art
from £45,000·ongoing · 6–18 monthsSystems, levels, characters, and technical art at full scale. Weekly builds, a shared roadmap, and a dedicated pod of engineers and artists working in your codebase.
- 04
QA, Porting & Launch
from £12,000·3–8 weeksCertification for PlayStation, Xbox and Switch, performance profiling, day-one patch pipeline, and post-launch live support so your release week goes quietly right.
