The usual suspects: level/difficulty completions, skull collection, terminal collection.

A good mix of some challenging ones:

Complete an entire Remixed Campaign without dying

With the Floor Is Lava Skull activated beat a mission without jumping or dying

Eliminate Captain Keyes and trap his six avenging Marines in the Autumn’s observation pen.

Complete The Silent Cartographer without shooting, using grenades, melee, dying, or restarting

(How do you not restart? Do you need to fully go back to the campaign menu if you fail?)

And of couse, LASO, which will be very interesting with all of these skulls.

I am surprised, but thankful, to not see a Legendary Remixed campaign achievement, but it seems like Remix mode is limited to six skulls anyway.

Ugh I was really hoping for no LASO lol. If it's *ALL *all skulls, maybe Acrophobia / Adaptation will help make it bearable, but I am expecting it to just be the classic skulls (sans 0.00x modifier skulls).

I am going to do my best to exercise patience and wait for it skips/tricks to be found.

I beat Halo 5: Guardians on Legendary before the 3 Warden skip was found, and Halo Infinite LASO (with the Tank Gun) before the Invincibility glitch and skip to the Road glitch was found. I am happy I got it done, but would have liked a little less frustration, haha.

Like always, they will be the last things I check off on my list.

Bro one of the new skulls is the floor is hot lava.

Laso is going to be absurd.

No way I would have been able to beat H5G on legendary without the three warden skip, that’s crazy

It was so excruciating that I can remember the frustration 10 years later, that fight on Legendary was probably harder than Infinite LASO haha.

Here’s hoping for some great tips / tricks in Campaign Evolved!
