Active Lancer (2003)

Join Lancer Squad, an elite unit of flight-capable troops, on their current mission to battle an extraterrestrial army set on taking control the universe's evil war machine. Active Lancer confronts you (and a companion if necessary) against waves of alien spacecraft, tanks, boats, and gun turrets over 15 stages of increasing difficulty. It's straight-up arcade shooter action with vertical scrolling. It has fifteen levels of vertical scrolling shooting, five hope-shattering monsters, three upgradeable weapon kinds, each with their own sort of charge shot, three distinct pilots, each with their unique strengths, and two-player action over a network or on a single machine.
