I've never really stuck it out in Champions Online, I tend to get a bit bored of it rather quickly. It's certainly not due to lack of content, however. The game's brimming with it. The latest update, Champions: On Alert, promises to add even more to the tight and cape loving free-to-play MMO.
Heroes will be able to duke it out against supervillains in classic scenarios, build faction reputation to unlock new travel powers and gear and experience deeper customization with gear modifications. Crotch cannons that shoot sharks? One can only hope.
