woot i beat the whole game with a defender lvl 34 and trust me if ur stuck on "One Final Effort" just get a shield and a pistol with dmg and long range with the killstreak ricochet and for skill get adrenaline and camp at 1 of the jet get your killstreak use ur killstreak to capture mid lag and if ur dead keep alternating ships(w/space/up arrow to eject parachute)
