Between short rides, spend coins at stations on train cars, weapons, drone slots and buffs. Merge cars to strengthen them and unlock more module slots; between runs, use the permanent upgrade tree.

Your first run
Start with the ride–station–upgrade loop. Your drones shoot automatically; you are building the train that supports them. The official feature list describes short rides between stations, with difficulty increasing as you travel.
- Finish a ride and reach a station.
- Review the available cars, weapons, drone slots and buffs before spending coins.
- Reorder or merge cars when the build needs a change.
- Between attempts, open the permanent upgrade tree.
Keep the two upgrade systems separate
Station purchases shape the current train. Permanent upgrades improve later attempts. Learn what each purchase changes before trying to optimize everything at once.
For the train system, read cars, merging and module slots. For progression between attempts, read permanent upgrades.
Launch-version note
If trade rewards disappear after resuming from the main menu, the developer has announced a fix. Update before assuming this is an intended penalty. This overview is based on the launch description and hotfix, not an independently tested best-build route.
