10 Video Game Achievements That Take The Longest Time To Unlock
3. LASO Master - Halo: The Master Chief Collection
It can be extremely difficult to fully complete a game. Getting 100% completion on several games is bordering on impossible. And getting 100% on four different titles on their hardest difficulty level is the kind of madness that will drive you insane for hundreds of hours.
However, that is the challenge that the makers of Halo have laid out for the franchise's most dedicated players. LASO Master is an achievement that requires you to beat four Halo games on Legendary difficulty with all of the skulls turned on (LASO literally stands for "Legendary All Skulls On").
For those unaware, skulls in Halo games are effects that can be activated to make the game even more challenging than it already is. Most people struggle to beat the game on Legendary difficulty alone, so adding all of these random modifiers into the mix is downright masochistic.
On top of that, you have to take into consideration that in order to complete all four of the games normally, you already need at least 34 hours of time. With the inclusion of additional challenges, this number becomes approximately 800 hours.
