Yes. Backers who pledge $1 or more will get access to the Crowd Ox pledge manager after the Kickstarter concludes. Through there you can upgrade your pledge to any reward level, and add additional products or add-ons.
Items ordered as Extras in the pledge manager will ship with Consumption: Food and Choices from this campaign. If you’d like to receive your Extras items sooner you can pre-order them through our website or find them at a local game store where available: https://kolossalgames.com/shop/
