There are three game modes in Overcrowd: A Commute 'Em Up:
- Procedural campaign: Build a network of stations in the procedural campaign, procuring more tech and hiring staff as you go. Return to past stations when you have more resources and try to earn a full 5 star rating!
- Sandbox mode: Define everything from money, staff, map size and win/lose states. Make the game as easy, as hard or as creative as you want.
- Commute of the day: Build a station on a randomly generated map, unique to that day.
