Throughout the sprite sheets I've made, a good chunk of them were never finalised due to multiple reasons. So rather than leave them unfinished in a throwaway folder, I've decided to compile them all here so that anyone can still find some use for them.
Some of the sheets were made to help projects (such as Metal Slug Forever or Metal Slug 5 Elite), and others were simply meant to be full fledged sheets to be posted on The Spriters Resource. So feel free to do whatever you want with them!
