10 Video Game Achievements You Only Get For Being A JERK To Other Players
4. Bully Mammoth - Armello

In Armello, a digital board game about a medieval fantasy version of Zootopia, you contend with three other players to become the realm's next king.
You're naturally incentivized to hinder your opponents in order to win, which is why it's inevitable that you're going to be a jerk to all of them.
Or just be an extra mean jerk to only one competitor if you're looking to get the "Bully Mammoth" achievement.
"Bully Mammoth" is a reward for choosing one specific player as your target in the game and making them miserable by killing them at least 5 times in a single match.
The achievement is specifically designed for needlessly tormenting other players, as in an average game, you won't ever have to go up against someone this many times, let alone kill them.
In fact, trying to get the achievement might make it harder for you to win the match, seeing as you have to leave the other two players be, so if you go on a vendetta against one specific person, it's clear you're either doing it out of spite or you're one callous achievement hunter.
