Charge up 5 hyper stocks during one hyper activation. (Arrange A)
In ARRANGE A mode, when you use your hyper, you can still charge up the hyper bar by killing enemies. What the achievement wants you to do is use 1 hyper and fill up 5 bars of hyper. To do this, accumulate 5 HYPER items and wait for a crowded section with lots of enemies. Activate your hyper and kill the enemies until 5 hyper bars fill up. The hyper lasts for quite a bit so it shouldn't be any trouble getting this.
Locations you can attempt this:
- Stage 2, after the mid-boss
- Stage 3, before the mid-boss as you start scrolling down.
- Stage 4, before you start your decent into the bunker/cave
- Stage 5, at the battery cells.
