## Description
_Interlopers_ is a _Space Invaders_ variant that expands on the original game
by adding some new features. The basics are the same: the player moves his
ship left and right behind three sets of barriers while blasting away at the
aliens that descend from above. A major difference however is that it is
possible to acquire new weapons and special equipment between waves. This is
done with money that is occasionally dropped from the aliens. In addition to
money the aliens might also drop two power-ups: one that recharges the
player’s shield and one that provides energy to the special equipment. Due to
the shield the player here does not get killed instantly when hit but can take
some damage. When starting out the special equipment is a random teleporter,
but others such as repair units and guided missiles can be acquired.
