This is a game about bugs. Specifically, collecting international butterflies from all over the world, each one marked with a specific flag. Oh, but to do that you have to survive the onslaught of the other bugs... and ghosts and ufos and dragons and stuff. Good job you have your shooting skills to destroy anything that moves, and anything that doesn't! Every time you play check the menu screen to see how your butterfly collection is growing.
