Action Doom 2: Urban Brawl is a computer game released in September 2008 which runs using the ZDoom source port. It was mainly developed by Stephen Browning, with ACS scripting by Mike Watson and James Bauer. It is the prequel to the 2004 total conversion Action Doom, but has a different gameplay style. Whereas the original Action Doom was a sidescrolling shoot ’em up using Doom’s first-person perspective, Action Doom 2 instead simulates a beat ’em up.
