Admittedly, this is functionally the same game as UA2, but the ninety new missions make up for it. Still, I think a great improvement would be improved guard AI and a map editor.
The most important rule is to not panic. If you panic you will press the wasd keys instead of the arrow keys or vice versa, and end up walking into a spike or falling off in the red screen or missing the box.
As someone who has played shattered plans, I can safely say that this game bears about as much similarity to Shattered plans as does Star Wars, basically, same setting, but the game is totally different.
