10 Video Game Achievements That Take The Longest Time To Unlock
4. Giant Accomplishment - Call Of Duty: Black Ops II
If you ever thought that any of the challenges in Black Ops II took a long time to accomplish, then what would you say to an achievement which can only be obtained by completing all of them?
That's right, the "Giant Accomplishment" in Call of Duty: Black Ops II requires the player to finish all of the challenges in the main campaign. Luckily, this doesn't include the challenges in multiplayer and the zombies mode, but you will still be looking at around 80 challenges in total in a campaign that normally takes 7 hours to finish!
The game has eight missions to complete, each containing 10 unique challenges. This means that you will be spending a long time trying to get them right before moving onto the next stage, which will increase your standard game time significantly.
The worst part is that the entire time you'll need to be extra careful about what you do with your safe file, as starting a new game will erase all of your progress on the challenges, forcing you to redo every single thing you've accomplished.
