I was lucky enough to design those characters and assets for a UA marketing campaign for Tilting Point company.
Everything was done for use in ads for the videogame Food Truck Chef from the developer Nukebox Studios.
You can download the game for Android and IOS.
Those chefs are the Spicy Team. They give you what you need for your special dishes, bringing the less and more spicy ingredients to you. The color key of they uniforms is black and red. Their logo is a “jalapeño” designed as an old school tattoo. Every character has a different level of spicy dishes.
