Phalanx is a futuristic shooter where you play as Wink Baufield, a genetically enhanced pilot flying the Phalanx , a prototype starfighter. The planet Delia IV in the Andromeda galaxy has been taken over by an unknown alien force, and it's up to you to protect and reclaim it.
You'll fly through eight levels, starting with locations on Delia IV and then invading the aliens' base. Like most shooters, you can upgrade your weapons by collecting bonus items dropped by enemy craft.
