Uridium 2 is a sci-fi horizontal-scrolling shoot 'em up created by Graftgold for the Amiga and published by Renegade in 1993.
The first Uridium was created for the Commodore 64, and it became one of the most popular shooters not only on the Commodore computer but in all 8-bit platforms.
Andrew Braybrook, the original author of the game, was responsible for coding this sequel. Actually, it's more an "enhanced remake" rather than a sequel since it's mostly the same game, just bigger and better.
In Uridium 2, you control a Manta Class Fighter, and you need to destroy 4 massive enemy dreadnoughts. To do that, you will have to survive waves of enemies and then find a way to land and plant bombs. As in the original game, the ship can change direction and move both to the left and the right, making the mechanics more peculiar.
The gameplay is excellent, controls are perfect, the graphics superb, and the music is a real gem. Even though there is no AGA version, some brilliant additions are visible only if you have an A1200 (or an emulator).
Last but not least, You can play Uridium 2 in co-op with a friend (or with the computer), which makes this shooter totally unmissable.
