This weekend between April 19th-21st Guild Wars 2 will be free all weekend to those who can snag a code from various promotions around the interwebs. You have a good chance to get said codes by following them on Twitter or Facebook, where they will announce giveaways to the masses. If you already have a trial account from the last free weekend back in November, you can sit back and relax, as you can continue right where you left off.
Once you get your grubby hands on a code, head over here to make your account and download the client. It’s a big one so I wouldn’t put it off for too long.
The free weekend starts at 12:01AM PDT on Friday, April 19th and ends at 11:59PDT on Sunday, April 21st.
