R-Zone 2 is very similar to the original in graphics and gameplay. There are a few minor changes, some extra tile types and a lot more levels.
New Features: There is now an audible alarm when the radiation reaches danger level, so you don't have to keep one eye on the indicator. However, the alarm is very much a last-minute warning. You have to move as soon as you hear it.
R-Zone 2 has a pause mode, activated by pressing the spacebar. The playfield is blanked during the pause mode, so you can't use it to plan your route!
There are 3 new types of tiles. Permanent (rivetted) tiles do not disappear when you pass over them. Blank tiles are just like tiles which have already been passed over, and must be avoided. One-way tiles are marked with arrows and only let you move in the direction of the arrows.
The original game was quite limited in scope and the lack of variety made 9 levels about right. The new tile types allow for a wider variety of puzzles,
so R-Zone 2 has 32 levels.
