Destroying blimps You can jusy use a
satellite or artillery strike to blow up the blimp in levels
that do have them.
Special Domination match If you happen to have two players on Domination match with no
AI players, each person can control three emitters, if at all possible
the ones by their base. This will allow each player to have an
equal "army" of drone tanks. This can also be done
with three players, with each player having two emitters. Also with
four players, there will be an uneven amount of emitters so that
they can stay neutral or players can fight for control of them.
This special Domination match can't be done with CPU controlled
opponents as they will try to capture every emitter. This match
can be fun, especially on certain levels.
