Infinite Crisis isn't in beta yet, but the launch trailer (embedded past the break) makes it clear that there are already several alternate versions of iconic heroes planned for inclusion. Players can also look forward to destructible environments, major events, and even an overall story arc. If you're worried about breaking your wallet, the game is already planning on launching as a free-to-play title, so everyone can jump in for all of the DC-related antics. You can sign up for beta testing now on the official site.
