Liberation Maiden is a mech-piloting shooter originally made available as part of Guild01. The player flies Kamui onto the map and the Touch Screen is used to fire missiles or lasers at enemies. At the end of each stage exists a Spike which can be revealed by firing missiles or lasers around its location. They are considered bosses and their thick armor can be pierced using a special technique that requires rapidly drawing circles on the Touch Screen.
