Save with fully upgraded heroes (level 10 for each, even the locked hero), fully upgraded upgrade tree and maximum number of stars.

I didn't open each hero, because I didn't want to bother with upgrading heroes and upgrades, but at the same time not to reveal the rest of the gameplay at once, so as not to spoil the impression :)

Drop the file to the address: C:\Users\*your account name*\AppData\Roaming\kingdom_rush_alliance or press the key combination Win+R and enter %appdata%

P.S. I edited the .lua save file in Wordpad by trial and error, so if you want to customize something for yourself, you can get there yourself.
