so I really liked some of the flavor text bungie released for stuff around halo 3, which mostly consisted of quotes from marines and other human personnel about what it was like to use these weapons or vehicles or to fight against them.
there are some similarly good descriptions in halo 5, but for the most part they fall into one of two categories: descriptions that are incomprehensible without deep lore knowledge, or descriptions that solely exist to explain lore.
Destiny did a pretty good job with its flavor text, and Titanfall did as well on its “burn cards”. I think the main problem is it seems like every one is written by the same person, from the same perspective of the halo universe. It would be nice if there were more quotes from people who’ve used or developed the items, and also if the descriptions were only purely functional when they’re talking about actual gameplay, and even then wove some more colorful sentences in there.
EDIT: some examples
“Recoil isn’t as bad as you might expect, but not because of any sophisticated dampening system – it’s because the damn things weigh so much.”
—Anonymous UNSC Serviceman (about the Spiker)
“It’s almost a direct analog of the BR55. I just wish it had a more — um — conventional scope.”
—Anonymous serviceman (about the Carbine)
“Speed is the only protection this vehicle provides; it is unarmored, noisy, and prone to roll-over. It demands a level of skill from its operator that is impossible to expect…during combat conditions.”
—Anonymous E2-BAG/1/7 serviceman (about the mongoose)
and then there’s some stuff that is more the style of halo 5’s good ones:
“Banshees of legend warned of death, and today all UNSC veterans know the cry of this glittering alien terror.”
