Beats of Rage

About

Beats of Rage is a customisable video game engine made by Senile Team and inspired by Sega's classic Streets of Rage series. With Beats of Rage, users can create their own beat 'em up games - no programming experience required! Beats of Rage was first released for DOS in November 2003. It was not advertised in any way other than by word of mouth, yet it soon gained enormous popularity. Ports to many other systems (e.g. Dreamcast, Linux, Windows, GP32, GP2X, etc) soon followed.
