Wave defenceIn development
Wave Attack
Pirates are storming the beach and you're all that stands in their way. Dig in, man the cannons and hold the shoreline as each wave hits harder than the last.

SilvesterHQ is a privately backed independent studio building FPS and indie games for s&box, an AI development tool that helps anyone make them, and websites that stand out.

Coming soon · Our dev tool
AI-powered game development for s&box
We're building a tool that uses Claude Code to help developers make s&box games — turning ideas described in plain English into working C# gameplay code, so you spend less time fighting the engine and more time making the game fun.
- Describe it, play it. Explain the mechanic you want and get s&box components you can drop straight into your project.
- Knows s&box. Designed around s&box's C# component system, so the code fits how the platform actually works.
- Battle-tested on real games. We're building it alongside Wave Attack, SO19 and Tooled Up Hunting.

Now in development
Three very different games, one goal: make something you'll want to play again the moment the round ends. They're also where our dev tool gets put through its paces.
Tactical FPSIn development
SO19
SWAT, but British. A tactical shooter about planning, teamwork and precision — stack up on the door, check your corners and clear the building the right way.
s&boxFPSTactical
Comedy shooterIn development
Tooled Up Hunting
A deliberately ridiculous hunting game where the bolt-action rifle stays at home and the automatic weapons come out. Subtle it isn't. Fun it absolutely is.
s&boxFPSComedy
s&box
Built on s&box. Facepunch's game platform pairs Source 2 with C#, letting a small studio iterate quickly and get games in front of players sooner.
Learn about s&box ↗The studio
Small team. Big ideas. Zero filler.
SilvesterHQ is an independent studio, which means every decision comes down to one question: is this fun? We'd rather ship a tight, memorable game than a big, forgettable one.
JamesFounder · Game developer & web designer
Gameplay first
We prototype the core loop before anything else. If it isn't fun in a grey box, it doesn't get art.
Ship, learn, improve
Small releases, real feedback, quick updates. Players shape the game as much as we do.
Personality over polish-by-numbers
Pirates on a beach. Miniguns in the woods. We like ideas with a hook you can explain in one sentence.
How we build
An AI-native studio, powered by Claude
We use Claude, Anthropic's AI, as a core part of how we work. It lets a small studio move like a much bigger one — so more of our time goes into the bit that matters: making things fun.
Claude Code everywhere
Claude Code writes, reviews and refactors our C# gameplay systems, powers the dev tool we're building for s&box creators, and built this website.
Prototype in hours, not weeks
New mechanics go from idea to playable test fast, so we can find the fun early and throw away what isn't working.
A tool, three games, one lean team
AI-assisted development is how a small studio can build a developer tool, three games and a web design service side by side.
Where we're heading
- NowBuilding, privately backed
Our dev tool and three games in active development on s&box, supported by private investment.
- NextCrowdfunding & early access
A crowdfunding campaign to bring players in early, plus early access to the dev tool and open playtests.
- LaterLaunch & grow
Release the tool and our games on s&box and grow into a sustainable independent studio.
Web design
Websites with the same attention to detail
Alongside our games, we design and build websites for game developers, creators and small businesses — fast, distinctive and easy to look after.
01
Game & studio sites
Landing pages, press kits and devlog hubs that make your project look as good as it plays.
- Trailer & screenshot showcases
- Wishlist and community links
- Press kit pages
02
Small business websites
Clean, modern sites that explain what you do and make it easy for customers to get in touch.
- Custom design, not templates
- Mobile-first and accessible
- Clear calls to action
03
Launch & hosting
Deployed on Cloudflare's global network so your site is fast everywhere and inexpensive to run.
- Domain & DNS setup
- HTTPS and performance tuning
- Ongoing updates on request
This site was designed and built by us with Claude Code — it's a good example of what we do.
Privately backed. Crowdfunding soon.
SilvesterHQ has raised private investment to get our tool and games off the ground. Next up, we're opening things up with a crowdfunding campaign — so players and creators can back what we build and be part of it from day one.
Let's build something fun.
Want early access to the dev tool, to playtest our games, to talk investment or to get a website that doesn't look like everyone else's? We'd love to hear from you.
