The Untouchables is set in 1920s Chicago, where Eliot Ness and his team aim to take down notorious gangster Al Capone. Based on the 1987 film by Brian De Palma, the game follows a similar storyline, with players taking on the role of Ness and his crew as they navigate through levels to bring justice to the city.
The gameplay in The Untouchables is varied, with some levels featuring traditional platforming and shooting action. Other levels require players to take on gangsters in a first-person shooter-style game mode, where they must blast their way through enemies while avoiding taking damage. With a mix of time limits and objectives, such as killing a certain number of enemies within a set timeframe, the gameplay is challenging and requires quick reflexes.
