Last Battalion

In 21st century, an alien race known as Kron began to prepare for an assault
on the Earth. A defensive station was built on Uranus, but after a while
communication with it was breached. A young pilot manages to avoid enemy fire
and get to the station, only to find out that alien ships are everywhere and
he must defend his corner of the space from them.

_Last Battalion_ is based on Override. Most gameplay features remain the
same, including three hit points per life for the playable character,
strength-enhancing power-ups, color-changing secondary weapons, etc. However,
the stages are different in layout (e.g. the game begins in space rather than
on planet surface) and contain different regular and boss enemies. This
version also offers selectable difficulty levels and other settings (such as
the amount of initial lives), and includes anime-style cutscenes that were not
present in _Override_.
