Arachnoid

_Arachnoid_ is a fixed screen shoot ’em up where the player takes control of
a spider that has to defend its eggs from hostile ants. The game is most
similar to Centipede. The ants attack in rows, moving horizontally one line at
a time until they get to the player who moves around in the lower sections of
the screen. Unlike Centipede there are no obstacles when starting out, but as
the player shoots his web at the ants a wall of webbing is created. These
causes the ants to change their direction. In addition to ants there are gnats
and flies that can carry ants and open up passages in the wall. There are also
wasps that moves across the screen at times. The game goes on until the eggs
hatch or they have all been taken by the ants. Once the eggs hatch the player
moves on to a new and tougher level.
