Here is the full list of all 23 Walhall achievements.
Like a blue hedgehog!
One after the other!
Deceiving death itself
Babies make you tougher
You're gonna love 'em
Copying enemy movements
A new challenger appears!
Gotta shoot fast
Button 2 is more useful now
He also wants to hit
He lost his drill for...
You're feeling tough
It gets spiky
Helps hitting your target
At last you can watch it
Speed up!
Your actions are under control
Take me seriously!
I'm gonna catch you!
As if it wasn't hard enough
REAL blue hedgehog!
Thank you for playing!
You're the real champion!
