Express 404

Express 404 is a roguelite train-driving game about transporting passengers through endless storms while watching for a mimic among them. You must meet each station’s money quota before the train arrives, while deciding which passengers to trust. Every ride differs, and mistakes cost money.

Drive through the storm

The train moves only while you hold the lever; when you release it, its speed drops. You monitor maximum speed, acceleration, drag, lightning rate and duration, and distance to the next station. Reach the quota by arrival or fail the run.

Find the mimic

There are 4–8 passengers on the train, and one is a mimic. It can kill only during lightning flashes, when brief clues may reveal it: red eyes, movement or a missing silhouette. Kicking the wrong passenger costs profit, while ignoring the mimic costs lives. It grows hungrier the longer the ride lasts.

Upgrade the train

Between stations, you can buy upgrades that change how a run plays. These can increase lightning frequency, reduce the safe time between kills, let you profit from dead passengers, boost maximum speed, increase the chance of a kill, reveal subtle signs, manipulate hunger or turn chaos into income. You can build around fast delivery, suspicion control, a high-risk death economy or strategies that exploit lightning, and combine upgrades to push the system before the quota catches up.
