## Description
_IAS_ is a sci-fi horizontally scrolling shoot-em-up. The player controls a
fighter craft, defending a human space colony against the onslaught of enemy
ships and mechas. The gameplay is similar to most other games of the genre and
involves shooting or avoiding the incessantly advancing enemy craft while
collecting power-ups on the way. The latter are distinguished by their color
and change the player character’s weapons, including laser fire, missiles, a
slow yet powerful charged energy shot, etc. The secondary weapon has to be
activated with a separate button and functions somewhat differently than in
other comparable games, specifically targeting enemy missiles. The player
character’s health is measured by an energy bar; once it is depleted, the game
is over.
