- Occaisionally, you will see two robots in deck chairs. Moving the cursor
over them will identify them as Brad and Allan, those two guys from all
the cut-scenes. They don't do anything while they're there, and clicking
on them will make them go away. In other words, they're completely
useless, just don't be surprised if you see them.

- With the PC version, if you play a modem, serial or network game, all of
the levels are automatically enabled in the "Replay Level" menu item. It
can help sometimes, if you don't feel like doing all the hard work.

- You will notice that if you move the cursor over a unit, next to it's
name there will be a star. At first, I thought it was an indicator to how
many kills the unit had made, but then I got a crane with a green star,
and it obviously didn't kill anything. It is apparently how many battles
the unit has been involved in. White is none, Green is one and Yellow is
two or more. Destroying buildings and bridges does not count.
