Food force is an Edumarket game published by the United Nations World Food Programme (WFP) in 2005. Due to its content, it is considered a serious game (game with educational purpose). Players take on missions to distribute food in a famine-affected country and to help it to recover and become self-sufficient again. At the same time they learn about hunger in the real world and the WFP's work to prevent it.
