The Rise of Hex is a side-scrolling 2D platformer with 3D models where the player controls Ben Tennyson in his attempt to stop Hex from taking over the world. It is the fourth game game based off the Ben 10 animated cartoon series. It is also the third game in the Alien Force brand and the first to be offered only as a digital download. The game uses typical platformer gameplay where Ben needs to climb ladders, jump from platforms, find keycards to open doors and fight enemies. He can also slide and fight with his fists.
His most important tool however is the Omnitrix. Through this device he can eventually transform in up to ten different alien forms. They have their own health and a unique fighting style with a primary and a secondary attack. The included aliens are Swampfire, Brainstorm, Big Chill, Humungousaur, Echo Echo, Chromastone, Jetray, Spider Monkey, Goop, and Lodestar. Each alien also has a special ability. Swampfire can grow plants to reach higher areas for instance, while Brainstorm can send out an electrical shock to enable or disable mechanical equipment. Morphing can be done at any time without restrictions and many of the abilities need to be used to solve minor puzzles.
