They look like a neon coloured sixpack of cans strapped to a tap. That's alright for the 4star version because I don't have to look at that one for very long, but the 5 star version should be something else. That's the main reason I don't have any alchemers, even though I have almost every other gun, including the ones people usually like to complain about (pepperbox, iron slug).
If you're ever doing a graphics update for some guns, I want alchemers to be the first. I'll even draw some suggestions if you want.
And?
Where's the suggestion? How about you come up with some ideas as to what Alchemers should look like, instead of just saying make them better.
