Okay,thanks.

My friends say they got it from drops,The keys are like CS:GO pretty much just skins is what you get from the keys and crates.

On unturned you can only buy a gold account,which costs like 5 dollars,But some people who dont have gold do actully get cards.
I also play unturned quite alot,I havent spent any money on it though

Idlemaster doesnt play my free games,It only plays the paid ones,Which i dont want cards in,Games it plays : Grimoire Manastorm
Games i want it to play : Unturned And Airmech
Help please!
