The year is 1930 and the black market for liquor is more lucrative than ever, and Al Capone is making higher profits than anyone from this illegal business. You are cast as Elliot Ness, who is going to do the job cops won't do (going after the ruthless Mafia boss and stop the flow of illegal liquor for good) along with a small select group.
The game is a classic action platform shoot em up retaining some of the film's story and style. You have various tasks throughout the six levels and a variety of weapons to pick up such as a shotgun or Tommy gun to use against Capone's gangs.
The gameplay perspective changes from level to level. At first, you run into Capone's liquor warehouses where 10 of Capone's accountants are running scared carrying valuable evidence in the form of ledger pages. The bad guys do their best to avoid you by leaping around the crates and shooting in frenzy against you. In the next level, gameplay changes to a third-person Cabal-style shoot em up which is set to a bridge where trucks loaded with liquor try to pass. There you need to shoot certain bottles of whiskey, avoiding enemy bullets from snipers and running foes. At the next level you need to take down certain foes in an Operation Wolf-style shoot em up. Believe it or not, at the next level gameplay shifts from 2D side scrolling to top-view multidirectional in which Eliot must go through the Central Station shooting incoming foes but at the same time, protecting a baby (rolling freely) in its stroller from enemy bullets! Of course at the next level the gameplay changes again, in such, you need to free a witness who's taken hostage by one of the bad guys, and the whole scene is running in a shooting gallery-style. In the final stage you chase Capone himself across the roof of the court building in a 2D horizontal scrolling action.
The untouchables is an enjoyable game, with each stage being different in style, both graphically and in terms of gameplay, so there is plenty of variety here, packed with some cute graphics and sounds.
The Atari ST version is graphically great, but offering a few less detailed screens when compared to the Amiga. The game here is using up to 16 colors on screen, and everything looks quite brighter here (but this is due to a coloring palette mismatch, because the Amiga version is ported directly from the Atari ST using its palette and adding the few extra colors of the Amiga hardware - same as Midnight Resistance issue!
). Sprites are nicely drawn and smoothly animated, whilst background scrolling move quite smooth without major glitches. As already said, each stage has its own graphics and perspective, and this adds a lot to the overall presentation of the game.
The sound here is good, offering several SFX of gun-firing, screams and explosions but not sampled. The tunes the original soundtracks of the famous block-blaster.
