Still, much of the fun in Xconq is the potential for surprise. The theory of visibility in Xconq is that each side has a layer of coverage, which basically just counts the eyeballs looking at each cell. As your units move around, the coverage in each cell goes up and down. Any cell with a coverage of zero is not currently being viewed by any of the side's units.
The unit property see-always
is useful for units like towns,
which are unlikely to disappear secretly.
These two parameters apply recursively, so for instance a city could be
see-always
and see-occupants
,
while a building in the city is see-always
and not
see-occupants
, with the net effect that units
inside a city can be seen by everybody,
but not when they enter a building.
