Boss battle: H3O - phase three | Episode 8 Remember Me Guide
Last update: 11 May 2016
Start by attacking the new mutants to accumulate Focus again. Pay more attention, than earlier, to dodging the shockwaves generated by H3O.
Do not hurry too much to launch the special actions and try to accumulate at least two full units on the focus gauge. Start by initiating Sensen DOS, which will reveal the cube that remained invisible.
Just like in the case of the first phase, you cannot break the cube with regular attacks so, you additionally need to use the Sensen Fury. If you have acted in accordance with my suggestions and accumulated two units of Focus, you will be able to start sensen fury straight away. Otherwise, you will have to attack the mutants. The good news is that the cube will not disappear in the meantime so, you do not need to hurry that much while accumulating Focus.
After you destroy the first cube you, of course, will have to repeat all of the actions to destroy yet another such object. Start by attacking mutants to replenish the Focus Gauge but, also speed up the process of regeneration of the previously used special moves. After you accumulate enough focus, initiate Sensen DOS and then Sensen Fury.
After you destroy the second cube, a Weak Point will appear next to the boss. You need to watch out even more because, the enemies are not going to disappear this time and you will have to avoid not only the bombing but also the mutants. To attack the weak Point, I recommend using the Junk Bolt only. Thanks to this, your stops will only be long enough to take a single shot.
Destroying the Weak Point will play a cutscene. Wait for Nilin to land on the shelf next to H3O and initiates the Sensen Fury. Start attacking the boss. You need to land around 30 hits but, H3O won't be able to defend itself so, this is only a formality.
Congratulations. You have managed to defeat the End Boss (the reward is as much as 3000 experience points) so, watching the final cutscene is the only remaining thing to do.
