Darius (the initial title) was successful in the arcades due to the three-screen display. The Edge software team have taken ages converting this Taito coin-op, and just like the arcade counterpart there is no plot. It is simple: lay into nasty bug-eyed alien hordes with every weapon at your disposal. This game features a different weapons system than in the other Dariuses. There is a pellet shot which with an upgrade turns to a strong two shot, then next a spread three shot and the large laser. Darius+ is so hard you can never get weapons to match the enemy's! Unlike the other ports this one has been completely redone and it looks a bit more like an R-Type game than anything else. During flight, while destroying certain enemy objects, you can increase the armament of your fighter ship by catching various power ups much like the R-Type series. After you successfully fly the pattern and destroy the enemies, a huge (classic aquatic lifeforms) creature will appear. By destroying the creature you can select the next battle zone. At first glance one would assume the bosses were decent ports from Darius. Well most of them play quite different from other games as there is a system of parts you have to blow off before defeating a given boss. Worse of all, you have to learn where they are and they can only be damaged when its they turn to be shot only.
Well, although a good shooter, unfortunately the difficulty of Darius+ is too hard to have more fun or motivation to play more than a few minutes. The ship is so slow moving it's almost impossible to get out of the way in time. And when destroyed, you lose all your extra weapons acquired. And the bosses at the end of each level are impossible to destroy when no advanced weaponry is used. So easily a dead meat. Just play this game the aid of a trainer if possible.
Graphically the game is good. The Atari ST version sports more colors than its default 16 colored screens and up to 2 layers of parallax background scrolling. The game though runs slower when compared to the Amiga version, with several frame-rate problems especially when too many sprites occupy the screen. Most of the levels have this fishy, sea-bottom atmosphere but with several sci-fi touches. Sprites move ok and are well designed especially the end-level bosses.
In terms of sound offers a music score (a very well composed one, which unfortunately is the same in every World) along with some typical shooting SFX (not sampled here). I may complain for the 3 channel sound generator of the ST here, as during gameplay it is frustrating to listen SFX and music at the same time as most of the music is cropped when SFX are set (so better to choose either music or SFX only).
