I'm happy to announce that Dead Frontier 2 now has Steam trading cards!
For every $9 you spend on the game you get one random card (either regular or foil) and if you're already spent money on the game you'll get up to 5 cards right away. If you gather a full set of cards you can craft a badge to display on your Steam Profile. This can be repeated multiple times to get higher tiers of badges. You can also earn special emotes and backgrounds.

NOTE: Trading cards are a Steam feature and I don't have any control over how the system works or how cards/badges/emotes are granted.
