GRFs are small extensions to OTTD's graphics. A GRF could be a new bridgetype, a whole new trainset or a new cargo type. #openttdcoop is using a compilation of GRFs to make our gameplay even more addictive.

#openttdcoop uses a certain set of additional GRF's. You will both need them to play on the Sandbox as well on the Mainserver. To ease things up, we zipped the GRFs needed into one single file. Simply download it, extract them into your /bin/data-subfolder of your OpenTTD-directory. Get the whole zip-file DOWN FOR MAINTENENCE. The GRFs will be automatically loaded if you access our servers.
