SCARLET NEXUS

The EXP bonus MAX is 1.80x and can easily be obtained by activating the brain field (available after Phase 4) in a large group of enemies, killing them as fast as possible.

In this video guide I will show you how to raise the EXP bonus to the maximum. This is actually pretty easy, the max is X1.80. All you need is a bunch of enemies and keep using the RT ability to quickly kill the enemies to raise the multiplier and the achievement will pop no problem.

I personally obtained this in Phase 6, whilst in the “Supernatural Life Research Facility”. I would recommend making a save at the start if you want to get this quickly. This area is great for enemies.

The maximum EXP bonus is 1.80, however you cannot get this in regular combat and must instead use Brain Drive and then Brain Field to be able to max the bonus.

When you get to the above area, progress normally until your Brain Drive bar fills. Get the kills as quickly as possible once it’s active and run around the entire area and keep finding enemies. You can get up to 1.50 EXP bonus with Brain Drive. Also, the EXP bonus will remain if you’re out of combat, as long as the Brain Drive didn’t run out.

Find a set of enemies before you’re about to run out of Brain Drive, activate Brain Field and whack away any enemies around you to get up to 1.80 bonus.

I got this here by coincidence, but once I noticed I was halfway EXP bonus through normal means, I straight up went for it and got it successfully first time with relative ease (Normal mode).

After learning Brain Field, Kunad Highway (where most people get the bus achievement) is a good spot for this. Gather up the enemies, then press and together. Next, kill them all. There are more than enough enemies to get the achievement.

Now, exit to the main menu, reload the checkpoint, and ride the bus down the highway.
