It does some things I've never seem before in an OpenBOR game. You start with 3 characters but you can unlock up to 82 trough an addictive system of collecting tokens by defeating bosses. It has 3 difficulty options for all types of gamers.
It has an open world approach (or universe would be more appropriated). You can choose which stages to take on first and keep progressing.
Characters have 3 or 4 special attacks, depending if you are holding a direction or running. Some stages have the classic sidescroller run n gun and other are action platformers.
This game will provide you with countless hours of fun by the huge amount of content it has. Once you finish the stages you can reset and keep unlocking stuff. Oh, nnd don't worry, you can save you game at any time and use 3 different save slots.
It is a must play for any fans of DC and beat 'em ups.
