"Remember! Kill the creeps for extra coins!"
So I've been away for some time, and lately have been getting into Dota 2. It's real fun! and The heroes you get to pick are plentiful, so you don't get bored playing as one or two heroes each game.
Anyway, when you kill creeps (Enemies you see running down what you call a lane), you get money. You get to hear a noise. All I did was mix the Coin Sound from SMW, and the Dota 2 money sound.
