DC Universe Online and a bit more ... actually-in-development than Marvel Universe Online, expect a treat at this year's San Diego Comic-Con. Gazillion will be showing off Super Hero Squad Online at Marvel's booth with "dozens of Marvel's iconic Super Heroes, combat missions, and social spaces all available for all con-goers to play."
Gazillion will also be showing off the game's headquarters system, touted as the most "in-depth housing system ever created for an MMO." We're unclear why the big push for a superhero MMO wouldn't be the "flying around" system or the "punching things really hard" system, but there you go.
If you're going to look up the game at SDCC, we've got all the info you need after the break.
