AIPD review for the Artificial Intelligence Police Department which is a twin stick shooter that brings some minor changes to the genre.
A.I.P.D doesn't bring a lot of new stuff to the twin-stick shooter genre, but it gets enough right that you'll most likely have a good bit of fun with it, providing the difficulty doesn't prove too much for you. - TGC
Like so many other would-be Retro Evolved usurpers, AIPD is an on-paper clone of Geometry Wars at best, sporting the look and ethos of the former game while lacking the depth and replayability that made it so great.
AIPD basically wants you to survive round after round of enemies getting gradually getting harder as you can imagine, but with each round offering a different challenge.
