A1: Block and hit

A2: Defeating Megatron is very, very hard! Try using L2. If you get away from him and lets say that you are standing in the corner, hold down L2 and make sure your cursor is on him.{right analog stick moves the cursor around} The longer you hold the L2 button down, the more damage Megatron takes. It depends on whether you get a clear shot or not. After he takes so much damage, he will shield himself and bodyguards will come out. Defeat any bodyguards that come out after you. If you keep up with Megatron, he will get mader and his bodyguards will get tougher. NOTE: When using the L2 button, it will drain the white bar and it is located underneath your health bar. I can't defeat him either but it works and I hope this works for you.

A3: Stun him with triangle square combo than attack

A4: I had lots of trouble with that also, if your looking to stay truthful, stick with anybody else, but if you get desparate, you begin to think of ways to heal yourself, this got me thinking, and then I looked in the intruction manual, and made a shocking discovery that I had never heard of, so if you press start on the first controller, then you plug in the second controller then press start, this will activate a second player and the second player can give you energy that you can use to heal yourself. so that you can finish the battle dont forget to hold down the block button in the proccess of transfering energy and healing, remember, people can take this as a cheat...

A5: I finished the game in 3 hrs you must press triangle 3 times to nock him down

A6: Now defeating Megatron is extremely hard you need to persist a lot and be ambitious.you need to evade a lot and use special attack at his minions.And try to use most of the energy to recharg your health.Oh and sometimes try to run from Megatron until you heal yoursel a bit.Good luck.
