From the back of the box:
'The Pixel Wars have begun! Take control of your pixellated heroes as you fight to control the world and defeat your opponent!
Each card can be used in a variety of ways, and only the player with the most cunning and tactical know-how will be able to use them correctly to gain the upper hand.
This straightforward war game can be learned in minuted, but remains fresh and exciting for repeated play-throughs.'
It came without the rules but with QR code and link to the rules on the publishers website.
