In this scene a injured Sweep crawls to Galvatron's feet. In the published version Galvatron uses his Heart of Darkness to restore him, but on the alternate page he takes a que from movie universe Optimus Prime and shoots him in the face. In the page comparison you can see the smoke rising from Galvatron's just-fired cannon and pieces of the dispatched Sweep in the background, where the published version has the smoke and pieces removed and the Heart of Darkness energy added.
