It's a two player versus shump which pits each player in an arena, where white enemies come down. The player can shoot these enemies to "capture" them and they will turn their color(P1 is Red, P2 is Yellow). That captured ship will fire at the opposing color with bullet patterns.
I included a (non working) one player mode in where your own ships shoot at you. There are 8 fighters, each based off of different shumps.
Here are some screenshots:
