Paragon Studios flipped the switch on a new free-to-play model for City of Heroes, now called City of Heroes: Freedom, last June. The superhero MMO hasn't seen a major content update since the switch, but that's all going to change soon, an announcement on the game's website reveals.
Paragon announced the Issue 22: Death Incarnate update in a news post, running through some of the big feature enhancements, a mix of late-game content for high-level heroes, co-op outings for lower-level players and an assortment of costumes, powers and VIP-only (ie paid subscriber) content. There's no release date listed, but you can expect Issue 22 to arrive soon.
I don't play City of Heroes myself, but I imagine that fans will be able to make sense of the fact that the update directs most of its attention to the Dark Astoria location, which is now a Level 50 Incarnate co-op zone. You can read the full breakdown of features on the game's official website.
