Alpha game
Get instant access and start playing; get involved with this game as it develops.
Note: this is the alpha of Jet Combat Sim. It is playable now, it is not the final version, and it will keep changing. Expect new content, balance changes, rough edges and some bugs. If you are not excited to play it in its current state, wait to see how development goes.
What the developers have to say
Why an alpha?
We are two brothers and a small studio. The game is already fun to fly. Selling the alpha lets us ship updates often, hear what pilots like and what they do not, and pay for the next big pieces of work: the campaign and multiplayer.
How long will it stay an alpha?
The alpha is out now (Oct 7, 2026) and stays the alpha until the final version. Each big update ships as soon as it is ready, not all at once at the end.
What is planned for the final version?
- A campaign with cities, villages and roads you can destroy, on a map with a moving front line.
- Multiplayer free-roam servers with proximity chat.
What is in the alpha today?
Playable now: 26 fighters and attack jets, 7 bombers, 4 transports and a spy plane, Career mode with credits and a hangar, Ranked low-pass scoring with a world leaderboard, guns, missiles and flares, destructible terrain and an endless world with three biomes: forested mountains, desert canyons and tropical islands. Windows and Linux.
Will the price change?
Yes. The alpha costs US$9.97 now and US$15 once funding goals 1, 2 and 3 are released in the game. If you buy now, you get every update up to the final version, including the goal features, at no extra cost.
How do you involve the community?
Our Discord is where we talk with pilots: bug reports, plane requests and votes on what comes next.
About this game

AI Generated Content Disclosure
The developers describe how our game uses AI Generated Content like this:
- Pre-generated content that ships with the game:
- Interface: the menus and the in-flight aircraft HUD artwork.
- Aircraft 3D models: every aircraft model.
- Music: every track, made with Suno.
- App icon: the game's app icon.
- Development tools: code is written with help from Claude Code, an AI coding assistant, and is reviewed by the developers.
- Live-generated content: none. The game does not generate any content with AI while it runs: no AI-driven dialogue, images, audio or text at runtime.
How we make this game: what we can make by hand, we make by hand. What we can afford to pay for, we pay real people to make. We use AI tools only when there is no other way to get the game out. Generative AI allowed me to give my vision to the game, and then we will make something better out of it, and more polished.

FAQ
Why is US$15 crossed out?
US$15 is the price once goals 1, 2 and 3 are released in the game. Today, the alpha sells at US$9.97.
Is this the final version?
No. Jet Combat Sim is in alpha: everything on this page is in the game today, but development continues. Expect new content, balance changes, rough edges and some bugs. Your Pilot Licence includes every update, up to and including the final version.
What does the US$9.97 Pilot Licence give me?
The alpha, playable now, with every update up to the final version, including the features unlocked by the funding goals.
Do I get the funded features?
Yes. Every Pilot Licence includes the features unlocked by the funding goals: the campaign at 4,000 licences, multiplayer at 6,000.
If I buy here, will I get the game on Steam?
Yes. Everyone who buys Jet Combat Sim here receives a free Steam key when the game launches on Steam, sent to the email used for the purchase.
Windows says it protected my PC. Is the game safe?
Yes. Windows SmartScreen shows this for new games from small studios until the download has built up reputation; it isn’t a virus warning. Click “More info”, then “Run anyway”. If your antivirus quarantines the file, restore it and add an exception. The Steam version won’t show this warning, and we’re working on signing the download.
What do I need to run it?
Windows x64 with a DirectX 12 GPU, or Linux (glibc 2.39+, Ubuntu 24.04 or newer) with a Vulkan GPU. 8 GB of RAM (16 GB with integrated graphics). 90 FPS on an RTX 2070. Virtual machines and cloud PCs are not supported.
What is adaptive pricing?
Jet Combat Sim uses a fixed price table, inspired by Steam’s regional price recommendations. We detect your country from your connection when the page loads. Where we list your local currency, you see and pay a round local amount in that currency, for example ¥1,380 in Japan. Seven markets (Turkey, Argentina, Venezuela, Egypt, Azerbaijan, Bangladesh and Pakistan) pay a lower US dollar price, US$6.27 instead of US$9.97. Every other country pays US$9.97. The price shown on this page is the price charged at checkout: no currency conversion is added afterwards. We are not Steam: the game is sold directly by JBro Studio, and payment is handled by Stripe.
Is there a Mac version?
Not yet. Tell us you want one:
