Great news, the AirMech Trading Cards have been approved and released! Anyone who has already spent money in AirMech through Steam will have up to 5 drops waiting for them, and additional drops are earned at a rate of 1 for every $9 spent through Steam.
The drop rules are Steam's, not ours, so any help with them or Trading Cards in general should directed to Steam Support. Carbon cannot give you cards, or make drops happen, thanks for understanding!
