More sketches again, this time technical stuff- more specifically turrets. I made these when I was imagining what sort of turrets would I make if I could make a tower defence game(sort of). They're divided into tiers, but in fact the two first make little sense since there's so different types compared to the ones that come later. I suppose you could say they're the "basic" level turrets and then the rest are better divided into three categories: anti-infantry turrets which have autocannons, gatling guns and lasers, short-range artillery which are comprised of cannons, multi-barreled cannons and rotary cannons and finally rocket artillery which have different sizes of rockets and missiles(some of them MIRV). There are some other considerations as to how they're categorized, but I think it's fairly obvious. Or not.
