Since the sprites have already been seen, there's been fan recreations, Matt n I were planning to release it all once part 2 dropped, and he is likely going to redo them himself anyways, here's the official Hank Redux Sprites.

Gun sprites, including ones that haven't been used or seen yet.

These were going to release eventually anyways so whatever, do what you want with them.
Also despite on-going rumor, no, I am not back and do not have plans to return.
