Dear Strategists and Rail Masters,
The long-anticipated sequel to the creative tower defense title Loopstructor has arrived. Rail Defence: Eldritch Siege is officially unveiled, and its Steam store page is now live.
View game page
Building on the original’s signature Loop-based Tower Defense mechanics, Rail Defence: Eldritch Siege pushes the concept further than ever before. Step into a mysterious steampunk world warped by the influence of hidden Rail Gods, design rail networks, deploy and upgrade unique Battle Trains, and harness new systems such as Rail Enchantments to transform your mobile fortresses into devastating engines of defense. Every decision matters, and every move could mean survival — or collapse.
The core elements that made the series highly replayable remain, now expanded with deeper customization and progression. Unlock diverse trains, unique bases, and powerful relics to craft your own tactical builds, then hold the line against endless waves of ancient nightmares on a battlefield that is always shifting.
Want to experience it firsthand? Save the dates:
January 30, 2026 – Limited-time Public Playtest begins. Be among the first to play and help shape the game with your feedback.
March 2026: The game's free playable Demo will officially launch! You'll be able to dive into the early content without barriers and enjoy the thrill of rail planning and fleet assembly.
Add Rail Defence: Eldritch Siege to your Steam Wishlist to stay updated and be notified when the playtest goes live. The rails are your final line of defense against the unknown.
We also invite you to join our Discord community to share ideas, feedback, and suggestions with the team:

Dear Loopstructor experts, we will also release new discounts in this spring sale. Welcome to purchase and play!
We are also pleased to bring you the update of v1.7.5, which includes a series of experience optimizations and bug fixes, aiming to bring you a better and smoother gaming experience.
Experience optimization

The unlocking order of Monster Main Base has been moved forward: We have adjusted the unlocking requirement of Monster Main Base from completion difficulty 20 to completion difficulty 16. Everyone can unlock earlier and use Monster Main Base to challenge higher difficulty.
Achievement data synchronization: Achievement data related to the cumulative number of kills has now been synchronized with the kill data in the atlas.
Pictorial interface optimization: When entering the game, the help interface jump button in the lower left corner will be restored.
Main menu refreshed: The main menu interface restores the classic style.
Super Module Improvement: The super module scattering projectile has been optimized, removing the restriction that new shells do not have elemental effects. Now, you can fully unleash elemental power and create more genre combinations in battle. It also fixed the issue where the "acceleration" collaborative module in the shell tank group could not take effect.
Bug fix

Pick-up train interaction issue: Fixed the issue where the ejection prompt was left on the field due to pick-up train interaction under specific conditions.
Bullet locking issue: Fixed the issue where new shells created by scattering projectiles would lock onto friendly units.
If you encounter any problems or have any suggestions during the game, please join the Discord:https://discord.gg/TJqVnDErNz for feedback.
Wish you a happy gaming experience!
