About OpenTTD
OpenTTD is a business simulation where players earn money by moving passengers and cargo using road, rail, water, and air transport. It expands the 1995 Transport Tycoon Deluxe concept with open‑source development and community contributions. Players build and connect industries and towns on huge procedurally‑generated maps, managing a multimodal network that grows with technological advances. The game supports solo play and a range of multiplayer modes, letting friends cooperate or compete across platforms.
01 / THE GUIDE
Gameplay Basics
Players generate income by transporting passengers and cargo across four transport modes. The core loop involves linking producers with consumers to complete production chains and earn profit.
Network capacity must be expanded as towns grow and demand rises, preventing delays and keeping revenue flowing.
- Start with short routes to quickly recoup vehicle costs.
- Monitor town growth to anticipate when to upgrade stations.
02 / THE GUIDE
Map and Terrain
Maps are procedurally generated up to 4096 × 4096 tiles, featuring four climate types with varied geography such as oceans, rivers, and mountains.
These natural features influence route planning, requiring bridges, tunnels, or ferries to maintain efficient connections.
- Use the terrain view to locate natural chokepoints before laying tracks.
- Plan around mountains early to avoid costly tunnel revisions later.
03 / THE GUIDE
Vehicles and Networks
A fleet can include hundreds of vehicles, each assigned to roads, rails, docks, or airports. Vehicles can be transferred between stations to balance load.
Stations can be expanded and upgraded, allowing higher capacity and faster loading times as demand increases.
- Group similar cargo types on dedicated lines to reduce congestion.
- Upgrade stations before adding more vehicles to avoid bottlenecks.

Multiplayer Options
OpenTTD supports single‑player and a variety of multiplayer modes, including online and LAN co‑op or PvP. Players can work together to complete production chains or compete for market share.
Cross‑platform multiplayer is available, allowing Windows, macOS, and Linux users to join the same game.
- Set clear objectives with co‑op partners to avoid overlapping routes.
- Use LAN for lower latency when playing locally.

Mods and Customization
The in‑game content service lets players download community‑made mods, adding real‑world vehicles, new industry sets, and custom scenarios.
These additions extend replayability and let users tailor the experience to personal preferences.
- Try a new industry set to experience different economic challenges.
- Back up your save files before installing large scenario mods.
