About the OpenTTD browser project
The OpenTTD browser destination here is Epicport's hosted Transport Tycoon project. It offers a way to explore transport management in a tab, with routes, vehicles and connected production forming the core of the experience. Check the destination's current version and feature notes rather than assuming it matches a current desktop OpenTTD installation.
Controls and getting started
A mouse and keyboard suit the map, construction tools and small management windows. Start with a modest route so you can check scrolling, zoom and construction controls before building a large network. Epicport labels multiplayer highly experimental, so coordinate around its documented limitations rather than assuming a desktop multiplayer setup will carry over.
Files, versions and saves
Use the hosted loader's own instructions for assets and startup. Epicport's page says login is needed to save or load. Desktop modifications and save versions are not automatically compatible with a browser build. Check its current save workflow before investing in a long-running map. Gameplay and save durability have not been independently tested here.
