Reach for the Sky

Reach for the Sky is a shoot 'em up in the vain of Capcom's arcade classic 1942. You fly over the Pacific Ocean during the WWII and take down waves of enemy planes while avoiding their counter-fire. Weapon upgrades are earned if specific formations of enemy waves (different to each level) are taken down with no escaping planes. At the end of each level you have to battle with a giant bomber.
