Hey guys, did these in my free time. They're all PNGs, and since I don't have the best tools and time to make these into actual .DDS files, I'm only uploading what I have so far. I know a few of you managed to use my old icons and convert them into DDS files that read the black background as transparent, so if you can work your magic, go ahead, but otherwise, it might take me a while before I get to it (I'll be facing finals next week and I have to study).
Naturally, I re-did the original BW Zerg unit icons, I also did the Terran LotV icons adn the Ravager. The Disruptor (might edit it) and Lurker Den are from WoL/HotS files (Lurker might be as well, most likely, can't recall - in any case, the HotS one is different from the WoL one, it has some purple spots and a purple tint and they most likely had it replace the original icon), so you can probably find those, but the other ones are either custom made or edited.
I fixed the Hyperion and Sentry Gun icons because they were discolored and I re-did the Spartan, Griffon and Siege Breaker icons, because the ones in the game looked like they didn't fit with the rest (And I gave the Siege Breaker its own "Siege Mode" icon). The Turret is an idea for a defense turret with a canon and would basically be a drone tank that turns into a turret (Think Bastion from the new Blizzard FPS Arena game, Overwatch) and the last 2 Terran units are the "Cyclops" and "Gunbot". The Cyclops is a recycled Warhound that serves as a support vehicle (Caster) with a minor melee attack and it now sports a robotic arm. The Gunbot is a Terran medium-range shotgun-like infantry robot that can freeze enemy units and then destroy them at once with its shotgun (A different take on the HERC).
And please, feel free to use these icons. Especially for the LotV custom mod. Perhaps I'll even do some wireframes for them when I have more free time. ;)
