Unless Fayde was....making Chipper it....but if he was also a dev hero, there's only one other hero and I'm laughing at those that keep saying someone else that came out not long after the release.

Beginners Guide to make an UI modification
Well, gladiator and mk came after the release, so it got to be kraken or dw. And since kraken has been in game whole time, the answer got to be dw... I doubt its the last hero before offical release (1.0.0), but its best alternative out of those. In 2.0.0 HoN went f2p, but it was offically released at that phase...
But well, 5 questions done before this, so i think i can fail one, if the answer isnt deadwood
Deadwood was released like 5 months before the game's release...
Omg it was the last hero and it doenst matter how long before...
This is good for those who were around support S2 at that time.
