No Time To Explain Remastered had Steam trading card support added on 17 July 2015. There are 6 cards in the series, and you'll receive 3 cards at random for purchasing and playing the game.
This game is a remake of No Time to Explain, which also has trading card support. Although the cards are identical between the two series (aside from order), they are not compatible - cards from the two series cannot be combined.
At current, Badge Level 4 has Badge Level 5's artwork.
