Cyber Police ESWAT is a side-scrolling run and gun video game developed and released by Sega for arcades in 1989. Players take control of Duke Oda, a member of the Liberty City Cyber Police Force tasked with finding and arresting the city’s most wanted criminals, and eventually dismantling a terrorist organization planning world domination. In 1990, Sega released a Mega Drive/Genesis version known in North America as ESWAT: City Under Siege.
The gameplay is similar to Sega’s own Shinobi (1987), as the player has the ability to jump up and down between planes where possible. The goal of each of the game’s 15 stages is to find and arrest a specific wanted criminal, who is usually fought at the end of the stage as a boss. Duke is initially armed with only a single-shot pistol, but upon arresting the first three criminals and being promoted to ESWAT, Duke is equipped with a Power Suit with a mounted machine gun for the rest of the game. The suit also has access to limited-use special weapons which can be found within stages. However, both of Duke’s standard weapons require ammunition, without which the player can only attack with a kick. Additional ammunition can be found in boxes throughout each stage.
