Though Streets of Rage 2 plays very similar to its predecessor, it improves and refines much of the gameplay. The biggest change is the replacement of the original special attack, which was calling a police car to damage all on-screen enemies, with individual special attacks performed by each character, that depletes some of their health. Each playable character's move list has been expanded and edited to make them very individual to play instead of similar with different handicaps.
Enemies are also improved; all are given life gauges (previously only bosses used them) and names, and like the selectable characters, given bigger and more individual movesets. There are many new enemy types, including biker, ninja, kickboxer and robot.
There are also changes to the weapons that can be picked up. The knife has been tweaked, so the player can throw it at will, whereas in the first game the it could be thrown by accident by the player; as a trade-off, the thrown knife now does much less damage. A kunai has been added, with the same functionality as the knife. The baseball bat from Streets of Rage is replaced by a katana, which performs the most damage of any weapon in the game.
