Buy Australia Did It: End-of-the-World Railway Defense Business Steam Key

Welcome to the drained Atlantic Ocean seabed, where a catastrophic event has transformed a once-thriving ocean floor into a hostile wasteland. You are a mercenary hired to escort valuable cargo by train across this monster-infested terrain. Australia Did It: End-of-the-World Railway Defense Business splits its gameplay into two distinct phases that create a unique strategic rhythm.

Before each train departure, you enter the station defense phase. Here, you deploy and position your limited mercenary units to withstand relentless waves of enemies in tight, turn-based tactical battles. This is where careful planning matters—positioning, unit placement, and preparation determine whether your defenses will hold. Think of it as high-stakes chess where a single miscalculation can cascade into disaster.

Once the train begins moving, the game transforms entirely. Your prepared units engage in real-time autobattler sequences as the train travels between stations, facing massive monster hordes. The core mechanic that ties everything together is unit merging: combine your mercenaries to unlock over 1,500 variations from more than 30 base unit types. Each merge creates new unit types with different abilities and synergies, encouraging experimentation and buildcrafting. Your carefully optimized crew composition must survive the journey intact.

Australia Did It blends turn-based tower defense with reverse bullet hell mechanics—a genre fusion that demands both deliberate strategic thinking and explosive real-time execution. The game rewards players who understand unit synergies, positioning tactics, and resource management. Every run presents new challenges through variable enemy waves and station modifiers that force tactical adaptation.

This title appeals to strategy enthusiasts who enjoy deep buildcraft systems, roguelike progression, and games that punish poor planning while rewarding clever unit combinations. From Rami Ismail, the designer behind Nuclear Throne and Ridiculous Fishing, Australia Did It offers a smaller but distinctly unique experience for players seeking genre-defying strategy gameplay.
