My side mode desire

Instead of firefight or spartan ops, what I would want for the additional game mode in Halo 5 would be a bunch of trial levels for something on par with the ending mission of Halo 4. That level was so fun. Just have a mini campaign of those please lol.

By far the best weird breakaway section in the series (like the maw run, or space combat in reach, rails sections in reach, etc.).

I really enjoyed that section. It was like imo a revival and properly done starfox for the modern age.
