sentry0 is a fullstack game studio. We design, code, and ship a finished game — gameplay, UI, data and monetization — in under a week. We're just getting started, so our prices are low and our effort is high.

How it works
Four steps. One week. One finished game.
01
Tell us the idea
Send us your concept — a genre, a reference, or a rough doc. We reply fast with a plan and a fixed quote.
02
We build it
You pay half to start. We build the full stack: gameplay, UI, saving, and monetization. You get progress updates throughout.
03
You review
We hand over a playable build before the week is out. Want changes? Revisions are included until it feels right.
04
Ship it
You pay the rest, we hand off clean, documented code. The game is yours, ready to launch and grow.
What we build
Fullstack means the whole thing.
No half-finished prototypes. We deliver everything a game needs to launch.
UI & menus
Clean, responsive interfaces, shops and HUDs that look sharp and feel good to use.
Data & saving
Reliable saves, leaderboards and stats so player progress is never lost.
Monetization
Passes, products and shops built to convert — without ruining the player experience.
Anti-exploit
Server-side checks and sane limits so cheaters don't ruin your game on day one.
Clean handoff
Readable, documented code handed straight to you, so anyone can build on top of it later.

Straight talk
We're new — and that's the deal.
We won't pretend to have a hundred shipped games or fake five-star reviews. sentry0 just started, and we're hungry to build a reputation. That's the honest reason our prices are low: we'd rather earn your trust with great work than charge you for a name we haven't built yet.
So here's our promise to our first clients: we over-deliver, we communicate fast, and if the first build isn't right, you don't pay. Help us start strong — and get a full game for less than it should cost.

FAQ
The honest answers.
Do you have a portfolio yet?
Not a public one — we're a brand-new studio. That's exactly why our rates are low and our effort is high. Your project could be one of the first in our portfolio.
How can you deliver in under a week?
We scope tightly, build with a focused stack, and keep communication tight so there's no wasted time. Larger Flagship projects may take the full week; smaller ones land sooner.
How does payment work?
You pay 50% to start and 50% on delivery. We'll agree the exact amount and method when you reach out. If the first build isn't right, you get a full refund.
What if I need changes?
Revisions are included — we keep refining until the build matches what we agreed on. Big new features beyond the original scope are quoted separately and fairly.
Who owns the finished game?
You do. On final payment we hand over clean, documented code that's yours to launch, edit and grow.
