## Description
The beginning of 21th century saw mankind descend into a new Dark Age.
Ecological disasters led to rise of terrorism. The planet was engulfed in
chaos, and several countries started preparing for a global-scale war.
Meanwhile, the restored Soviet Union and Japan began a war of their own,
initiating as a conflict over Japan’s north-most island, Hokkaido…
_Kaien_ is a _doujin_ (freeware game by independent developer) vertically
scrolling shooter. The player controls a lone Japanese jet, making its way
through hostile areas, beginning with the defense of Hokkaido and advancing
into enemy territories. The enemies include other jets, helicopters, ships,
stationary cannons, tanks, and other military vehicles and machines. The
player-controlled jet has a basic attack with unlimited ammunition, as well as
several powerful attacks of limited usage, such as a fire blast that destroys
an entire row of enemies, etc. As in most games of this kind, the levels are
punctuated by mini-boss and stage boss battles. Running out of lives results
in the Continue screen, forcing the player to restart the level.
