All Aboard! The Train Defense Express

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!
