Upchuck Unleashed is a nice game appeared on our site in which Ben 10 needs your help to find and destroy the king of the knights. He is protected by his knights and you have to work hard to get over them to reach the king palace and destroy them before he conquer the city. In this game Ben 10 will use a special alien, Upchuck and you have to help him complete every mission. If you are hit by the knights you will lose energy so be careful and destroy them before they have the chance to hurt you. If you lose all the energy you have the game is over and you have to start the game from the beginning. Using the arrows you have to move with Upchuck and with space you have to eat things. This alien has to eat things to have ammo to shoot into the enemies. Using the space bar you have to shoot the enemies when you have ammo. At the top you can see the score, the energy you have and so on. As you progress in higher levels you will be on your own and you have to work harder to complete your goal successfully. Do your best to complete all the missions with Ben 10 and Upchuck.
