Full Steam announcements and update articles for this title.
The new “Online Co-op Mode” will officially launch on October 30! To celebrate the update, a special 20% OFF discount event will run for one week.
In this update’s “Expedition Operation,” survivors can team up with friends to form mech squads of up to four players. With limited ammunition, work together to search for supplies and resources to enhance your mechs. Make the most of tactical coordination within your squad to survive the brutal post-apocalyptic world!
In this mode, players can form mech squads of up to four members, while solo play is also supported.
Unlike the “Survival Zone” mode, ammo in this mode is limited. You’ll need to replenish it through supply boxes scattered across the map. Managing your ammunition wisely will be the key to victory.
Mech enhancement skills are no longer obtained through leveling up; instead, they’re gained from resource crates found throughout the map. How you allocate these skill upgrades to form an effective tactical synergy within your squad will test every survivor’s strategic planning.
Survivors, recruit your comrades and overcome a series of tough challenges to reach the final victory point!
Finally, we welcome all of you to keep supporting us and sharing your valuable feedback. Follow or message our official account, or join our Discord channel to discuss and exchange ideas with other players!
From September 30 – October 7, Iron Core: Mech Survivor is 15% OFF! The “Partners in Cluck!” bundle is also on sale with discounts up to 30% OFF. If you’ve been waiting for the right time to jump in, now’s your chance—gear up with the Mecha Squad and take the fight to the swarm!
Alongside the sale, “Endless Mode” is now live! Enter the Endless Apocalypse Trial, where relentless waves of enemies—and sudden boss encounters—will push your skills to the limit.
Upgrade your mech, unlock powerful abilities, and fight to survive as long as you can in this brutal gauntlet!
But the swarm keeps evolving, and going it alone won’t be enough forever. Reinforcements are on the way—your squadmates will soon join the fight.
In upcoming updates, we’ll be adding online “Co-op Mode,” so you can team up with friends and stand together against the apocalypse!
Survivors new and old are welcome to join our official Discord Channel!
Survivors, this is your chance—don’t miss it!
And here’s the big news: Online Co-op Mode is coming soon!
Team up with friends, form a 4-player tactical squad, and fight back against the apocalypse together.
In Co-op Mode, up to 4 survivors can pilot mechs, face relentless swarms, and unleash firepower side by side. Only teamwork will keep hope alive.
This mode introduces brand-new stage-based progression: break through area by area, overcome challenges, and push toward victory.
More details will be revealed soon—follow us for the latest updates!
Online Co-op Mode is almost here. Get ready to rejoin the fight!

Thank you for your incredible support! As of today, our sales have almost reached 10,000 copies! For a fully independent team of just five developers, this means the world to us.
At the same time, we’ve received a huge amount of valuable feedback from you — most of it focused on:
Performance issues in the game
Early-stage difficulty and balance problems
UI guidance and configurable settings
Based on your feedback and our designers’ research, we’ve been working around the clock — pushing 4 major updates in just 48 hours, with 22 feature improvements and 9 bug fixes, including:
Significantly reduced memory usage and package size, and major performance optimizations.
Adjusted early-stage levels and the first mech’s balance, allowing players to unlock and enjoy later normal-difficulty content faster.
Improved mission prompts and operation tips to help new survivors get through the early game more easily.
Major upgrades to Tower Defense builds — faster deployment, shorter cooldowns, and healing towers now repair nearby defenses. We’ll continue refining Tower Defense and other build-based combat!
Added toggles for damage numbers and controller vibration, and enhanced the range indicators and projectile visuals so you can keep better track of combat even in late-game chaos.
Thanks to these updates, the gameplay experience is already much better than at launch — but we know we’re still far from perfect, and we’re not stopping here.
Next, we’ll continue optimizing the game, including better controller support, clearer map objectives, and improved tower deployment controls. We’ll also keep expanding the game’s content to bring you even more to explore!
