Register here. One account gives you three pilots, which you create inside the game.
You need the Silent Death Online client and its data files. Put them in a folder of their own.
Run the launcher from that folder:
python sdolaunch.py --portal https://sdo.ennwise.com
It signs you in, writes launch.txt next to the game, and starts
it. Or download launch.txt yourself and run the game
within two minutes.
The game client has no login screen of its own. The service authenticates players and tells the game who they are: the launcher signs you in, the server issues a one-time ticket bound to your address, and the game connects. Nothing about the client's own protocol changes.
