We're letting you know that the mirror IP address for connecting to the EU servers has been changed.

This update is mainly done to improve in-game ping when using the mirror address.

The old address (212.23.211.20) was hosted in Germany and didn’t have direct peering with the data center where the actual game servers are located, which resulted in slightly higher ping.

The new hosting is located in the Netherlands and has direct connections to the game server data center.
Thanks to this, ping on the mirror has dropped by almost 10 ms!
The new hosting also offers better overall stability and connectivity.

That said — if the main server address is still reachable for you, 164.132.201.202 remains the best possible option.

New mirror addresses:

EU: 45.155.7.47:27015
EU+: 45.155.7.47:27016
EU Versus: 45.155.7.47:27017

Dear players and members of the CORE-SS community! The project administration cordially congratulates you on the upcoming New Year!

The past year has been a time of significant development for CORE-SS. We thank you for your activity and dedication!

Throughout the year, our servers have actively evolved — through numerous gameplay fixes and balance adjustments, as well as the addition of new content! Many new players have joined our servers and have seamlessly become part of our friendly community.

To celebrate the holiday, we held an amnesty for mutes and gags in the chat. We believe that the New Year is a time for a fresh start and more constructive communication within our large community.

Your passion for the game creates the unique and dynamic atmosphere of CORE-SS!

May the coming year 2026 bring you brilliant new victories! We wish you good health, personal well-being, and unforgettable moments in epic battles on our servers!

❄️ Winter event has ended ❄️ — time to sum things up!

During the event you diligently cracking open gifts, helped the team, warmed the gnomes, and shared the taste of New Year cola in the safe room, and on the Versus server you unimaginably deftly caught coins and gifts. Let’s highlight the players who paid special attention to this and took the top spots: Пчёлка (Coop), Shayk (Versus), Leon Sensei Ω (EU Coop), Iwatani_Naofumi (US Coop). They earned a truly impressive amount of points during the event. A reminder that active event participants who placed 1–10 won’t be left without rewards either. They will receive points equal to double the amount of points they earned, as well as a winter trail (except Versus).

Full results can be viewed here.

✨ Despite the end of the event, snowfall, radio, and Winter Path quest (with freezing weapons!) will remain on the server until the end of January. Holiday gifts will drop until January 10. Thank you all for participating! Merry Christmas! ✨

❄️ winter has arrived! ❄️


Dear players, we are announcing Winter Event!

Time to soak up the holiday spirit and take part in the exciting activities! Earn points on the Coop server by helping other players; carry cola and gnome to the safe room, collect gifts and collect coins dropped by special infected on the Versus server! Beyond all that, a mysterious artifact has appeared on the Coop servers... who will be lucky enough to possess it?

We are announcing a major update to the EU Coop-25 server! Over the past 2 weeks, we have been actively testing a new location for the European server. We have migrated to new dedicated hardware that can handle the most extreme load during the server's most intense and "chaotic" moments.

Recently, the old hardware could no longer cope with the increased load, and many players began experiencing issues joining the server due to a lack of available player slots. Because of this, the decision was made to expand. We have switched to renting a dedicated server, which has completely resolved the resource shortage issue and also allowed us to launch two new servers!

The existing EU Coop-25 has been migrated to a new server in a new location, from Germany to France, in the world's largest and Europe's leading data center! In addition, to solve the problem of insufficient player slots, a full copy of the game server, using the same statistics as the EU server, has been launched.

Furthermore, a new EU Versus server has been opened, now for European players! This server is also a copy of the main Versus server but features a new, separate player statistics system!

You can find the server addresses on our website or on the main statistics page.

We invite you to diversify your gaming experience on our new 🇪🇺 EU Versus server!
