4 more enemies, this time in the Space Merc Redux 16-colour palette (see my other subs), because it became clear that these assets belong with those ones.

Also included here are the first wave of Super Dead Gunner sprites, redone in the new palette. This submission is only CC-BY 4.0 because it includes those; you can consider the "batch 2" ones to be OGA-BY 3.0, because they aren't based on any CC-BY assets.

The walker mech is based on one by Ansimuz (CC0), from here: https://opengameart.org/content/sideview-sci-fi-patreon-collection

The flame is derived from one by Ben Hickling (CC0): https://opengameart.org/content/animated-fire

The original Super Dead Gunner sub is here: https://opengameart.org/content/super-dead-gunner-platform-shmup-enemies
