10 Hardest Video Game Achievements To Unlock
6. Seriously 5.0 - Gears 5
The Achievement: "Insane Campaign, Master Horde & Escape Launch Maps & Characters, 20 Re-ups, General in Tour."
The "Seriously" achievement has been a tradition of the Gears of War franchise ever since the beginning, and represents the ultimate challenge that each game has to offer, such that only players who put all other games aside for an extended period have much chance of obtaining it.
Gears 5's "Seriously 5.0" is characteristically punishing, requiring players to beat the campaign on its highest difficulty ("Insane"), beat the Horde and Escape maps on "Master" difficulty, get all launch characters to level 15, hit level 100 and re-up 20 times, and reach the rank of General in Tour Rewards.
Unless you really, really love this game and are prepared to put in months of leg-work while foregoing so many other quality gaming experiences, you shouldn't ever bother.
