In Halo 4, 5, and Infinite, Master Chief became a more nuanced, human character.
In spite of the Halo series’ struggles, 343 deserves praise for adding nuance and characterisation to the ever-beating heart of Halo - The Master Chief. Playing through Infinite, it's abundantly clear that the events of the current and previous trilogies have irrevocably changed the iconic hero. He’s no longer the ‘blank slate’ that was previously presented by Bungie. He’s a fatigued, damaged and fallible protagonist, and one who is meandering through currents of grief, while reveling in his newfound agency. Giving the Chief a compelling and meaningful voice was no small feat, and 343 should be proud of that victory.
This article completely misses part of the appeal of the original iteration of character in the original game trilogy. It was the Chief and Cortana vs an entire alien collective. The blank slate Bungie displayed in their games was genius, he was an mysterious hero a wide audience could identify with because he wasn't as clearly defined as most characters.
The books added a lot of lore and backstory but most Halo players just want a fun game with exposition that doesn't get in the way of gameplay, it's why the Cortana level in Halo 3 was derided.
Not every character has to be a damaged soyboy, a soldier has to suck it up and do his duty.
Chief and the halo franchise became a joke under 343
The 343i Master Chief has is based on the books. However, in Halo 4-Infinite, the Master Chief overtime become. gradually becomes more willing to show some emotion.
