I don't really know anything on this pixel art scale that is sci-fi oriented.
This, however, could be a good theme for a new pack. What must-haves would you like to see in such a sci-fi pack?
Well,
I can think about many different things, such as : guns, armor parts, energy shields, upgrades, bionics, tech stuff, computers, screens, mothercards, holograms, neons, lights, lasers, mutations, meds, pills...
I might buy this classic med-fan pack as well to support you if you do a sci-fi theme as sexy as that, haha !
