4) Seriously 3.0 – Gears Of War 3
You might have thought Gears of War 2’s incredibly difficult Seriously 2.0 achievement was tough, but developer Epic Games had more punishment lined up for players in the sequel. Seriously 3.0 is unquestionably one of the most brutal and quite frankly, irritating achievements ever conceived.
In order to pop Seriously 3.0, players will need to earn all the Onyx medals (by getting 6,000 kills for every single weapon in the game), take 1,500 enemy leaders as hostages, execute 6,000 enemies, revive 1,200 teammates, win 3,000 of 4,000 games, score 6,000 headshots, reload your weapon 25,000 times and perform an array of other tasks that all amount to an inhuman amount of effort to beat.
No, seriously, you will not look human after attempting this achievement.
