EDIT: added a few more guns and improved the shotgun animation

Here are some 16x16 sprites and animations for 5 guns (8 directions)

AK47, shotgun, handgun, sniper, RPG, LMG, heavy, raygun, flamethrower

the sprites were made using voxels in an orthographic setting,

and are coloured with 6 bit RGB palette

If there are any guns you want me to add let me know :)

Free to use for any purpose
