We’ve got a nice little animation showing an Ogre Titan pulling off an execution. As you can see, Titanfall isn’t just graphically impressive, but very stylishly made. Comments on this thread indicate that other Titans have different kill animations. For example, Striders will crush the pilot with their hand as seen below. Also, Titans need to be at melee range to pull off these executions, and have to be done from the front. Otherwise, the target may simply turn towards you.
And of course, to get your hands on these and other Titans, you need to get burn cards. You can check out our Titanfall Perks cheats guide, Titanfall ordnances cheats guide and tips and tricks.
