"The original Aqua Kitty launched with the first batch of PSM games back in October of 2012. To this day it is easily among the best games that PSM has to offer. Aqua Kitty DX maintains everything that was great about the original game while adding new levels, enemy types, boss fights, new game modes, graphical upgrades, cross-save/cross-buy, leaderboards, and even a co-op mode for those playing on PS4. It is essentially your “definitive” edition of Aqua Kitty.
As a refresher Aqua Kitty is a side scrolling shooter similar to Defender. The story tells of a future in which the milk reserves have run dry."
