This game was created for SFP/Verdesian to promote their NutriSphere-N product. Their product protects Nitrogen in the soil so that field crops have an abundance of it for the season. The game opens with a quiz to assess the player’s knowledge as well as educate them about Nitrogen. For each question answered correctly the player earns an extra life for the defending stage. Dropping into the game stage, the player controls the NutriSphere-N to protect the Nitrogen entering the soil while taking out the things that attack it. Once a player has touched the Nitrogens they move to the plant helping it to grow which improves your score and reinforces SFPs message. There were versions of this game for their website, a trade show booth, and a mobile app.
