I played the 4 missions currently available for Civil Unrest.
It has potential, but the 3rd person mod for Halo Reach is kinda shit. The weapons often don't shoot where you're aiming because of obstacles.
The gameplay is extremely trial and error. You're a made out of paper, but your enemies don't fare much better. Allies are powerful, but combat has so much RNG that encounters can go both ways if you don't get involved.
There are 4 armor abilities present, but only Dodge and Sprint are functional.
It's also one of the rare 3rd person mod that allows zooming.

The mod has BRs, the Halo CE AR (in addition to the Reach AR) and a Light Machine Gun.

Tactical mod made by an autist. Keep an eye on it.
