Primal Rage Codes -

Hint: Diablo's Pulverizer move:
Hold 1 + 2 then press Up, Down.

Hint: Quick kill message:
If you kill your opponent within then seconds a "Quick Kill" message will appear. Your enemy will remain dead on the ground. Note: This only works on the first round.

Hint: Flash of light:
Keep attacking your enemy and killing him. There should be a light change in the back ground. This is rare, but worth seeing.
