The object of Danger UXB is to defuse a ticking time bomb before its clock reaches zero. On the way to where the bomb is located you must consume as many blue tiles and flags as possible, by running vertically over a 15 x 15 grid. To get yourself in the same column as the bomb, you can slide horizontally across the tiles. This is also a useful move to avoid the skulls placed in your way.
As the tiles are eaten up, it becomes harder and harder to reach the bomb in time. Once six bombs have been defused, the grid is replaced, and the game becomes faster. At the higher levels of the game, stamping boots are introduced which impede your progress towards the UXB, and must be avoided at all costs!
Danger UXB makes full use of the BBC's graphics and sound capabilities. The animation is very smooth, and the movement keys extremely responsive. As for the sound, you are treated to a Scott Joplin rag, as you rush around the board for dear life as well as the usual zaps and explosion.
I found Danger UXB a refreshing change from shooting down aliens, attempting to land Concorde, or doing odd things with frogs. It's a mixture of tactics, timing, and reflexes, and it had me glued to the screen for hours on end. A very well written program, which I highly recommend.
