Dead Connection is an arcade game released by Taito in 1992. The game takes place on September 5th 1953 "in a big city somewhere".
It features a group of detectives who set out to fight a crime family. The game has a strong Film noir vibe, shown through the appearance of the detectives and the featuring of a female protagonist. Each stage is preceded by a short cinematic interlude that explains the transition between the game's different locales.
The in-game manoeuvres were unusually diverse for a sprite-based shoot 'em up game of the era. When the player moves his character to within arm's length of an enemy, the shoot button triggers a melee attack. The player can also lie prone to evade gunfire, and perform a diving somersault in order to quickly take cover behind tables, plants, pillars, statues, and other fixtures.
Instead of using scrolling each stage takes place against an unmoving but richly detailed backdrop beginning with the lavish interior of a posh hotel. Most of the environment is destructible and the scenery becomes visibly degraded by bullet holes throughout the prolonged firefights.
The game seems to take specific inspiration from the 1987 mobster film The Untouchables. Two of the main characters bear an unmistakable resemblance to Andy Garcia and Kevin Costner who both starred in that film.
