I dont know which unit makes the most disgusting sound but i always liked the overlords "BlAAARRAGGHTHHGHHHH!" from Starcraft 1. Its one of his move quotes.
In Polish one of Stucov lines are "Teraz juz nawet Lugola mi nie pomoże". This translates to "Now even the Lugola wont help me". This is refrence to Lugol's iodine that was distibuted in Polish People Republic (Poland under Soviet control) after the Chernobyl catastrophe to protect people from radiation and because of lack of iodine tablets. Also you forgot about Niadra voice lines. The queen that you control in one of HotS mission called "Enemy within"
2:22 - *Mortituri Te Salutant* was also the first line from the "Brood War Aria" which we first hear in the Brood War cinematic intro that introduced both Stukov and DuGalle.
There's also Czech song Morituri te Salutant by Karel Kryl. A vocal critic of communist regime in former Czechoslovakia, that ended up exiled due to his artistic expression. The song is literally about 1968 Soviet occupation of Czechoslovakia.
Ok that was short (Just like the SC1 Version) but still great. I hope that you mention the Voiceline changes with the Protoss Units. The Phoenix for example has ''I have a lot of nerve... cords'' but they changed that line in the Legacy of the Void campaign where one major plot point is that every Protoss cuts their nerve cords and therefore loses their connection to the Khala. That results in that Phoenix line being changed to ''I used to have a lot of nerve.. uhm.. hm.. Cords''. Those changes are also present in Coop Mission i think. The High Templar is the one that got changed the most.
The Kerrigan with the Echo-y voice is the one that, I think, is NOT available to the player. The infested Kerrigan that the player CAN control has some funny remarks if memory serves well. Still, good job. Hoping to see the "Tauren Space Marine" in the Protoss one! (You know, due to the campaign and the "konami code input")
"Those about to die, I salute you" could also reference "For Those About To Rock (We Salute You)" by AC/DC, and given how many lines from Starcraft 1 referenced songs (especially Duran referencing Duran Duran), I can see it being a reference
2:24 Morituri te Salutant is also a reference to that song that plays in the Brood War intro cinematic where DuGalle and Stukov are introduced (ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-OEUQ7Xkdz9g.html)
I think the Stukov line "Those about to die: I salute you" is a reference to the undefeated gladiator in... Gladiator: "We who are about to die salute you"
Honestly I'm surprised you missed the iconic Starship Troopers quote by the hydralisks, that one's a classic! The infestor also has some very subtle references to the Flood from Halo, which feels appropriate, considering how hard the Halo franchise cribbed on StarCraft
Hey, what about The Blob 1958? 1:14: Does the state of Russia still exist in the UED's "one- Earth, one-nation" dominion, though? Anyhow, Infested Stukov's second line brings into mind DC Comics' Bane more to me. 2:19: Isn't this also a gladiatorial greeting before the start of their bloody sport? 3:01: Albeit way too kinder than last time, woman.
The country of Russia is probably no longer independant, but Russian culture and identity probably still exist, and Russia likely remains as a sub-division, like how Texans or Scots are still a thing even tho they're a part of larger nation.
Do the infested Terran und Space-Marine no jokes too ??? or isha from the Zerg Campain ? or what about Warfield or Swan from the Terran campain ? all SC2 and i probably did forget some Units or heros too i would realy see a part 2 because i like those videos very much they very good made
Blizzard should’ve had a cheat code you could enter that would either translate what the Zerg say into English, or give them subtitles. Hilarity would ensue. Suddenly “BLASARRHG” becomes “I implore you to please stop clicking me”. Haha
