Warhammer 40,000: Space Marine 2

Pretty easy achievement to get. I'm guessing alot of people understand how to get this achievement but for those that don't, I will be happy to help with details.
Playing as Titus, his Y button ability is the righteous fury special. As you play through the campaign just activate the ability every chance you get and just kill enemies. Simple and easy.

I would like to note this is my very first guide so hopefully I was straight to the point for this and helps whoever may need info pertaining to this achievement. Happy hunting. 🫡

In order to get this achievement, you need to be playing as Titus and get kills while his Y ability is active. To play as Titus you must be the host of the lobby. His ability gives you a temporary stat boost.

A quick method I found for this achievement was to select Kadaku and play the second mission called severance. Right from the start you walk forward and there's two groups of tyranids. What you want to do is throw a grenade at the left group, activate your ability, then throw another at the right group. After that just shoot whatever's left until your ability runs out. Once it runs out press start and reload checkpoint. Rinse and repeat.
