Beating the hardest* level in 4 kingdom rush games at once

*Note: hardest is subjective. This is my pick for the four games, except for Vengeance. Treasure Island is harder but would be ridiculously, stupidly hard with this ruleset as the parrot would eat all my gold. And Dusk Chateau would probably be harder WITH THIS RULESET due to the micro required, but when played normally I believe Sunken Citadel is so I picked it.

So what are the rules? Simple. Beat the 4 hardest levels in the first four kingdom rush games at once, with 3 stars and on their respective hardest difficulty (and obviously no items). And I also disallowed selling. I reduced their resolution to 960*540 (aka half width and half height) to neatly fit them into 4 squares.

I have no idea how the hell that 1 guy on KRO leaked, KRO was always the easiest, that was the first time anything ever leaked and of course it had to be on the winning attempt.
Krv was surprisingly harder than KRO, but still very easy.
KR1 was kinda tricky but not too hard.
KRF was the bastard. Retried like 5 times cause something would always leak.

Press F for my desktop, which got all messed up because for whatever stupid reason the icons get all jumbled up when you hide the taskbar (which I had to do to have as much game on screen as possible for KRO and KRV).

Also, shoutout to this guy:    • 【Kingdom Rush Frontiers】Impossible challen...  

He also did something similar.
