Gromada’s artificial planet was built as a giant factory for new battle
machines. By constructing battle robots, cannons, tanks, helicopters, planes
and floating mines crowding the 20 fully animated (flora, fauna, fire, smoke)
arenas of the planet, the player can defeat the mysterious alien forces come
to destroy Gromada. Aliens also managed to gain control over all battle units
on the planet but Kassandra, a tank with enormous war features that can be
even upgraded and beefed up at the end of each mission. With this mouse-
controlled beast, you can accomplish all 25 leveled and unlinear missions
until you get control over Gromada again, by destroying all enemy machines (20
types in total). The multiplayer mode include particular bonuses for
achievements.
