I saw lots of charity skins in games such as PUBG, Dying Light. The main purpose of these skins is to collect money and donate to different charity organizations that are trying to help people with different problems connected with a natural disaster. So I think that unturned needs some sort of charity skin which will cost 1$ and all money from that skin is going to support fight against COVID-19.
skin from PUBG that was made to help maintain the situation with forest fires in Australia
this Vintage Gunslinger Bundle from Dying light was made to support COVID-19 relief efforts.
