"get up, you lazy shmups, and find yourself a job!"
shmup = shoot 'em up
Examples of some shmups are: Galaga, 1942, 1943, Fantasy Zone, Gradius, Salamander, TwinBee, Darius, Cotton, Truxton, Border Down, Under Defeat, Gunbird, Strikers 1945, Dragon Blaze, DoDonPachi, Deathsmiles, Ketsui,....
This list could go on forever, I chose some random old and 'new' titles to give some examples.
