About this game
Hop on board the ultimate train defense challenge! Build, upgrade, and strategize as endless waves of enemies threaten your precious Infinite Power Generator.
All Aboard! The Train Defense Express blends the best elements of auto-battlers, survivors, tower defense, and idle/clicker mechanics into a unique strategy experience. It’s easy to pick up, but hard to put down—don’t let its casual appearance fool you!
Your job is to protect the Infinite Power Generator by buying defensive train carriages to destroy incoming enemies, and economic train carriages to help generate gold. Choose carefully—only the right combination of carriages will allow you to survive the endless waves of enemies!

Level up your carriages by combining 3 of the same type and level to create even more powerful defenses! You can level up carriages infinitely, but it'll cost you.

It's essential to buy upgrades from the shop! Upgrade the value of gems so that each gem is worth more gold, and hire miners to automatically produce more gems for you.
Survive against the orc onslaught!

Patch v1.1 - Mobile release!
All Aboard! is now available on mobile platforms! Apple App Store (iOS 14+) | Google Play (Android 7+) I have a limited number of free promo codes for the new mobile versions to give away! If you'd like a code, send a request through our official contact form and let me know if you prefer iOS or Android. Codes will be given out on a first-come, first-served basis until they are all gone. Limit one per person. This offer is void where prohibited by law. (Note: Please make sure you enter the correct e-mail address! At least one person has entered an invalid e-mail address.) Anyway... This patch presents a new All-In screen, a UI overhaul (mostly for the benefit of mobile), and a new challenging difficulty mode! Let's get into it. All-In Screen Changes All-In, which unlocks at level 6, was originally intended as a bit of a chance game, where it had a chance to succeed or fail to upgrade your carriage. It eventually ended up as a simple way to mass-upgrade carriages. The interface for All-In is changing to be in line with this new way of thinking: Using All-In is now in general much faster than before, as it requires almost no work to calculate the result. You can now upgrade a carriage as much as you want in a single All-In attempt, for example, upgrading a Sniper from level 5 to 10, as long as you have enough gold. UI Overhaul The UI had to change a lot to accommodate mobile, but I also wanted to make better use of the screen space anyway. One of my favorite changes is how the information displays in the top-right of the side bar during gameplay -- it now uses simple icons instead of tiny text. If you prefer the old display, though, you can click on it to toggle it. 'Impossible' Difficulty The new "Impossible" difficulty is a special challenge mode. Unlike other difficulties, you will find it impossible to play for dozens to hundreds of hours, and that's because gold-generating train carriages are banished from the start. The challenge here is to see how long you can ...Read full article on Community Announcements (Likadev)Patch NotesOfficial

All Aboard! The Train Defense Express is released!
Here we are, finally at version 1.0! I'd like to thank everyone to played during the Early Access period. You all helped make the game better in every way, and I'm sincerely grateful for your feedback and bug reports. Thank you! I'd also like to thank my friends, sargx, Exolun, and SilentWizard, for their extensive testing, and Grisknuckle for helping out with some of the art. In other news: All Aboard! The Train Defense Express is now Steam Deck Verified! Enjoy, Steam Deck players! Let's discuss the patch stuff already. Wasn't this supposed to be a small patch...? New Content {STEAM_CLAN_IMAGE}/45348796/1de414f2ac0aef9a6ce60d7fd4ae36bbb4fbaf5f.png New Carriage Selection/Swapping View: The old way of viewing and swapping carriages was a little unpleasant, especially if there's a lot of junk on the screen, and especially if you're a controller- or keyboard-only player. Now, a new button appears when the game is paused that opens the new carriage view. The new view is functionally the same as before, but much easier to see what's going on, and it supports drag & drop. The old way of viewing or moving around carriages still works, but with mouse only. {STEAM_CLAN_IMAGE}/45348796/0bb918035bb6e0a4d6fc4a10e261dcd211cb15d9.gif Loot Fairy: A rare loot fairy may now randomly appear and wander around the map for a couple of minutes. The more you hit it, the more valuable gems it will drop. It's pretty hard to kill, though... 5 new boons: The final set of boons have arrived! Two of them cannot be unlocked until you've maxed out every other boon. A special surprise for dedicated players is behind those locked boons. Some placeholder art is still being used for this. 10 new relics: This includes more than one relic which requires merging other relics and a new starting relic. Some placeholder art is still being used for this. 3 new carriages: However, they don't appear normally. They have something to do with some of the new relics... 8 new achievements: Certain things that many...Read full article on Community Announcements (Likadev)AnnouncementsOfficial
Save & Continue have arrived!
Hello, gamers! I'm excited to bring lots of interesting changes with this patch! First of all, thank you everyone who responded to the "beta" branch test request! You've helped make this patch much better. Don't forget to switch back to the regular branch, unless you want to continue receiving unstable test builds. As we approach v1.0 release, I'm slowing down new features in favor of polishing, stabilizing, improving performance, and bug fixing the game. There are no new boons this patch. The last set of boons are coming in v1.0. However, there is a new feature that is definitely not small or insignificant - this one was in high-demand by many players! New Content Save & Continue: The long-awaited save/load system has arrived! You can now save your game and continue where you left off. The game automatically saves before/after every boss killed, when you open a relic chest, or if you close the game (either by closing the window or selecting "Exit to Desktop". If you get a game over, the save file is deleted. You can open the in-game Esc menu and select "Exit to Menu" to cash out your EXP and ticket rewards, if you want to receive EXP and tickets without having to Game Over, or you can select "New Game" instead of "Continue" from the main menu. Elite Upgrades: Upgrading everything in the "Upgrades" menu will now unlock a new window with a couple new things to spend money on. You better bring a LOT of money. 7 new relics! This includes a new starting relic, but how on earth do you unlock it...? The maximum level for new unlockable content is 60, where a fun new relic awaits you. New Display Option - Scientific Notation: When certain numbers start getting big (>= 1,000,000), display them in scientific notation. Changes Opening the treasure chests to buy new train carriages will gradually increase the price of each chest. This price curve has changed. It's a little more expensive in the early game, but becomes significantly cheaper the longer the game goes on. The draw...Read full article on Community Announcements (Likadev)
