Ben 10 Underworld is a free Ben 10 Games.
Ben 10 is one of the most powerful superhero, basically, because he is in the possesion of an alien device called an omnitrix, which gives him the power to transform himself into 10 different aliens, each having a special power and ability, so, obviously, all of the aliens want to get their hands on the omnitrix, so that they can defeat Ben and take over the world. Because Ben cannot be defeated since he can transform into such powerful creatures, Kevin decided to attack his family and kidnap Gwen, thinking that this way, he will force Ben surrender the omnitrix within 24 hours. But Ben is not easy to fool, he will fight for Gwen's life, he will try to rescue her with your help. Join Ben into this rescue adventure, and be very careful because there will be a lot of obstacles and robots that will try to stop you. Enter the Underworld along with Ben, and rescue Gwen. Good luck boys, have fun and do not be afraid of the mean aliens!
