Cyber Arena is back.
Since 2004 we've built digital worlds, browser games and online communities. We're reviving Cyber Arena as a modern gaming and AI entertainment studio — for players, builders, and people who still believe the internet can feel like a world.

- Human-crafted, technology-powered
Born in the Browsergame Era.
Cyber Arena was never built around a single game or a single technology.
It was built around curiosity.
From the early browsergame days of die-kreuzzuege.de to the Cyber Arena Fußballmanager and later the expansion into a multi-game platform, the mission was always the same: create worlds that people want to be part of and build technology that helps creators bring their ideas to life.
More than twenty years of projects, successes, failures and experience have shaped what Cyber Arena is today. Modern AI is part of our toolbox, just as web technologies once were, but it is not the story itself.
The story is about building, learning and evolving.
Today, Cyber Arena enters a new chapter — combining gaming, software and digital innovation while staying true to the spirit that started everything more than two decades ago.
- Browsergame Pioneer2003
die-kreuzzuege.de
One of Germany's early major browsergames. Strategy, alliances, late-night raids — pure pioneer-era browsergame DNA.
- Strategy meets Football2004
Cyber Arena Fußballmanager
Cyber Arena is born. Manager DNA at its purest: tactics, transfers, long seasons, real rivalries — built for players who stayed for years, not minutes.
- Persistent Worlds2003–2013
The browsergame years
A decade of running persistent online worlds, alliances and ranked seasons. The internet still felt like a place you could move into.
- Craft & Brand2013–2018
Webdesign studio era
Cyber Arena shifts gears and spends years crafting websites, brands and interfaces for other operators. Same care, different surface.
- Pause2018+
The quiet years
A long pause. The studio steps back. The world goes mobile, then AI. We watch, learn, sharpen — and wait for the right moment.
- Now2026/27
The comeback begins
Cyber Arena returns as a modern gaming and AI studio. Same spirit. Faster brain. Sharper systems.
die-kreuzzuege.de
One of the first and largest browser games of early German web history. Years of alliances, raids and forum lore. A symbol of where we come from — and a reminder of how durable a world built with care can be.

Argus&M OS
An AI team on every project
Argus&M extends Claude with any number of AI partners — Codex and others — working the same codebase. They all share knowledge, rules, skills and MCP tools and review each other on code, architecture and prompts. Not a single AI. An AI team that splits work, challenges results and ships projects together.

Future Tools
Experiments in motion
Small, sharp AI utilities for creators, operators, builders and digital teams. Released when they earn it — not before.
- Experiments
- Utilities
- Creators
- Operators
Built by humans. Sharpened by tools.
The studio stays deliberately small. One operator, a tight circle of partners and collaborators, and a stable of AI tools we built for ourselves. We ship slowly, in public, and we ship things we'd actually use.
Every project we touch starts with the same question: does this make the internet a more interesting place to live in? If the answer is no, we don't ship it.
Cyber Arena · Since 2003
Old-school internet spirit. Next-generation AI execution.
- 01Belief
Long-term digital worlds.
We build for years, not sessions. Worlds that compound, communities that remember, mechanics that age well.
- 02Belief
Games create community, not just sessions.
The best part of a browsergame was never the click — it was the people. We design for the people first.
- 03Belief
AI augments builders. It doesn't replace taste.
Models are leverage. Judgment, identity and craft stay human. We use AI to ship more of what we actually mean.
- 04Belief
We build tools and worlds we actually want to use.
If we wouldn't open it on a Sunday evening, we wouldn't ship it. Our taste is our quality gate.
Common questions. Honest answers.
01When does the Football Manager Closed Alpha start?
We're targeting Q3 2026 for the first invite-only Alpha round. Waitlist signups go in first; the order is roughly first come, first served, weighted by people who held an account on the 2004–2013 Fußballmanager.02Is the Football Manager free? Pay-to-win?
Free to play. Premium upgrades and cosmetics fund the game — but the simulation itself is never pay-to-win. No accelerators on match outcomes, no premium-only player attributes. Tactics, talent and patience win seasons.03Browser only — or also mobile?
Browser-first, optimised for desktop and mobile web. A native companion app will come later if there's clear demand. The persistent online world runs on the server, so platform choice doesn't fragment the league tables.04Is die-kreuzzuege.de coming back too?
Not as an active game. We honour it as legacy and may revive an archive view, but our focus is the new Cyber Arena world — Football Manager 2026/27 and the AI Lab tools.05What is Argus&M OS exactly?
It extends Claude with additional AI partners — Codex and others — working the same codebase. They share rules, skills and MCP tools and review each other on code, architecture and prompts. Not a single AI, but a team. Private preview Q4 2026.06How do I get into the AI Ensemble Tool beta?
It's bundled with the waitlist — one signup, all updates. Public beta is targeted for Q1 2027. The earlier you join, the better the slot.07Who is behind Cyber Arena?
An independent operator-developer team based in Germany, building since 2004. We've kept the studio small on purpose. More on the people behind the projects coming with the brand kit later this year.08What about my data and privacy?
GDPR by default — minimum collection, opt-in only, no third-party tracking. See the privacy policy for the full breakdown. The waitlist email is used solely for signal updates; one-click unsubscribe is in every mail.
What we're working on right now.
A live thread of what the studio is shipping. Updated when there's actual signal to share.
