In this Ben 10 Alien Force game you need to help Ben and Gwen disable all bombs in each level. To disable a bomb simply get close to it. You can't get to every bomb without help. Gwen will help you if you guide her to places with pink light. She can make new platforms appear. When you get enough Omnitrix power you can convert into Echo. When you're Echo, stand on the green lights and press space to use your scream powers and break nearby objects.
