How to play
To play on Sigil - City of Doors you need to own Neverwinter Nights 2 and both the expansion packs Mask of the Betrayer and Storm of Zehir.
Once you are patched up to date, you need to log on to multiplayer and find the gamespy listing of games. Under roleplay you will find Sigil - City of Doors. Press connect and the files needed will automatically start to download (this will take about an hour on average).
Once the files are downloaded you will be asked to create a character to join the server. Your character will be saved on server side.
Hope to see you in game!
