Build
Choose the model that you want to create, feel the satisfaction of snipping out the model parts, step by step build your model, and apply finishing touches, so it is ready for painting.

Get Creative

Showcase
Once your model is complete, that is not the end! You can set a scene in PhotoBooth mode and arrange your models onto different backgrounds, add cool effects and make them look even better! Share your work directly from the game to your Social Media channels and show it to others.
