Explore tiny planets, dodge aliens, collect coins, and use power-ups in COSMOS 404 to test your reflexes and chase your highest endless-run score online.
COSMOS 404 is a fast, addictive space runner where you sprint across tiny procedural planets, avoid strange alien creatures, and collect shiny cosmic coins. In COSMOS 404, every run is different, every planet feels new, and every second tests your reaction speed. If you love endless runners with a sci-fi twist, COSMOS 404 delivers a smooth, minimal, and surprisingly intense experience that keeps you coming back for โjust one more run.โ
The core of COSMOS 404 is simple: run forward, stay alive, and go as far as possible. But what makes COSMOS 404 special is how this simple idea is executed. The tiny planets are generated on the fly, the obstacles appear unpredictably, and the pace slowly increases. This means COSMOS 404 never feels repetitive โ instead, it constantly pushes you to react faster and think sharper.
Unlike complex games with long tutorials, COSMOS 404 is easy to start and hard to master. You can understand the controls in seconds, but mastering timing, positioning, and power-up usage takes real practice.
In COSMOS 404, you run across small spherical planets floating in space. Each planet has a slightly different shape, layout, and obstacle pattern. You must jump, move, and react quickly to avoid falling off the planet or crashing into hostile aliens.
The galaxy in COSMOS 404 is not empty. Hostile aliens roam the planets and block your path. Some move slowly, some suddenly appear, and some are positioned to trick your timing. Learning how to read the patterns in COSMOS 404 is the key to surviving longer.
Coins are scattered across the planets in COSMOS 404. Collecting them increases your score and rewards your risk-taking. Sometimes the safest path is not the most profitable one, and COSMOS 404 constantly asks you to choose between safety and reward.
The Speed Boost power-up makes you run much faster for a short time. In COSMOS 404, this is both a blessing and a danger. You can cover a lot of distance quickly, but your reaction window becomes much smaller.
The Magnet power-up automatically attracts nearby coins to you. This is perfect for players who want to maximize their score in COSMOS 404 without taking unnecessary risks.
As COSMOS 404 evolves, new power-ups and small gameplay tweaks can appear, keeping the experience fresh and surprising even after many runs.
COSMOS 404 uses a clean low-poly visual style that feels light, smooth, and modern. The simple shapes and soft colors make it easy to focus on gameplay, while the space background creates a calm yet mysterious atmosphere. This combination makes COSMOS 404 relaxing and exciting at the same time.
If you enjoy games that are easy to pick up but hard to put down, COSMOS 404 is made for you.
Staying near the center of the planet in COSMOS 404 gives you more time to react to obstacles.
As COSMOS 404 speeds up, stay calm and make small, controlled movements instead of sudden large ones.
Save Speed Boost for safer sections and use Magnet when coin paths are risky.
The magic of COSMOS 404 is that there is no final level. The only true goal is to beat your own record. Every run in COSMOS 404 is a personal challenge against your previous best. This creates a strong sense of progression and motivates you to improve little by little.
COSMOS 404 is more than just a simple runner. It is a beautifully designed, endlessly replayable space adventure that combines speed, reflex, and smart decision-making. Whether you have five minutes or an hour, COSMOS 404 gives you a satisfying challenge every time you play. Jump into the galaxy, start running, and see how far you can go in COSMOS 404.
