Arkanoid - Eternal Battle

You will be mostly playing AI opponents despite this technically being an online game mode. There is really no reason to boost this trophy with others as the AI is competitive but beatable. Also to note, a victory in this mode means not only beating all other 24 human or AI players, but also beating Doh at the end as well. Keep your combo going during the first part of Eternal Battle and then when facing Doh on your own you need to focus on keeping multiple balls going to deplete his health bar. The timer is tight against Doh so you will have many defeats despite taking "first".
