As opposed to the first installment, "Body Blows Galactic" in its 1-player mode gives the player the possibility to select a fighter from all available characters. However, there is no boss or any other hidden character.
Differences between ECS and AGA versions
The main difference between ECS and AGA versions of the game are the backgrounds of the arenas. In the AGA version, they are more colourful and some of them have an extra parallax foreground. Nevertheless, the colours of the fighters are still the same as in ECS version. One more difference of these two versions are the stars in the main menu. In the ECS variant they are just passing from one side of the screen to another in a straight line, while in the AGA version they are circling around, creating a visual feeling of depth.
