Guild Wars E3 demo client now available
The publicly playable demo won't official open until May 12, but early birds can now get the client file from DLX and create an account.
While most online games don't open up until beta testing begins, the Guild Wars E3 demo will let gamers directly participate in ArenaNet's online RPG for the three days of E3, May 12 to 14. To get gamers ready for that three-day window into the game, the developer is releasing the demo client early. GameSpot DLX is the first online site to offer the demo client.
You can download the client below, but I think you'll have to creat a free DLX account before hand:
