Undercover Cops is a beat'em up arcade game by Irem. Players control "city sweepers," who fight crime by beating up thugs. It is notable for its detailed backgrounds and grimy futuristic setting. The arcade version appeared in 1992; for its time it was relatively gory, featuring crow-pecked skeletons in the midst of its urban wastelands. It is much harder to find nowadays; shortly after its release, games of this type were largely eclipsed by one-on-one fighters like Street Fighter II. [source:wikipedia]
