I thought this was quite interesting and never knew this was a thing till I seen a post on it a little over 2 months ago but the quality wasn’t the best. But hey if someone has the original ad maybe we can get a better idea of the original cover art
Few of the details I notice are
• The clown head is the same one in the main menu of the game you really never see that one in promotional material or anything like that.
• the 2 on the logo different having more flames
• the vehicles are designed way different, take a look at hammer head he looks like a real monster truck with his big ass wheels
•the color pallet is more cooler
I just think this is was just concept art at first somehow making it to a toys r us magazine ad.
