Megatron and the Combaticons face Optimus Prime and the Protectobots inside an experimental factory to gain access to a new energy device, but instead of a head-on battle, a computer programmer named Ethan compromises they should battle inside his 'Battleworld' program. Both parties agree and Megatron is vanquished, but somehow returns back to life inside via a secret password (Afterlife), given to him by Combaticon Vortex. He almost defeats Prime, but is vanquished yet again by him. Unfortunately, because of that cheat, Prime innnocently killed some of the game's inhabitants, which forces Ethan to destroy Prime's physical body (as Prime has a 'no killing' code, which he mistakenly believed he violated when he defeated Megatron the second time). The Combaticons and Megatron then leave with the new energy device while The Protectobots leave with Prime's damaged body.
