Beginning March 4th, players will receive double XP, Influence, and Infamy for a three day stretch. It's an even better deal if you've pre-purchased Going Rogue, you'll be leveling twice as fast and wielding the Dual Pistols power set.
What about those City of Heroes players who have let their subscriptions expire, and are looking at the offer and thinking "well, too bad for me"? Nope, you're invited too. The double XP weekend is also Account Reactivation weekend, so you will be able to reactivate your account free of charge.
All of the information can be found here. So those of you with inactive accounts, download the client to be ready for the weekend. The rest of you, get ready to either dust off the alts or start planning a costume for a brand new character!
