When you are playing as Black-Suited Spider-Man, you can repeatedly tap the right bumper (RB) button to charge your rage meter. Now I'm sure you knew that already, as it does tell you, but what it doesn't tell you and what I've recently found out is that depending on your health, the rage meter will charge up at different speeds. The more health you have, the slower the meter will charge and the less health you have, the faster the meter will charge.

When you are going for this acheivement, when you splat into the ground make sure you die 25 times to het this acheivement
