10 Impossible Video Game Achievements That Totally Broke You

For those who don’t know, it stands for ‘Legendary All Skulls On Master.’ Not even this title alone can describe how much of a tough cookie this achievement is.

In Halo: The Master Chief Collection, the most important collectables of the game are skulls. These are game modifiers and mutators that can beef up the challenge quite a bit. Once you found them all, you need to crank the game up to the max difficulty and beat every level with all skulls activated.

That’s four games compiled into one.

While some skulls are exclusive to certain games, some effects include: turning your guns and every enemy invisible, doubling their health, making you unable to use alien weapons, disabling auto-aim and motion sensors, etc.

The worst of the bunch is the Iron skull - death on co-op mode means everyone must restart back to the last checkpoint, while on solo, you go back to the beginning of the mission. The threat is real.

Are there any positive effects? For the most part, not really. The goofy skulls like “IWHBYD” will make rare dialogue more common, while “Sputnik” will allow you to smack scenery around much easier, for makeshift covers during gunfights.

Nonetheless, this truly is the stuff of nightmares, even for hardcore Halo fans.
