In Halo 3, as of the ODST update, I noticed a bug that wasn’t in the flight.
On Mark V Spartans (we tested Mark VI with no bugs), Pearlescent visor colors appear very strangely. They seem to screw up the visor’s default texture/design (the little lines on the visor) and offset them and stretch them in a weird way that is asymmetrical and very clearly unintentional.
I believe it is due to the Halo 3 ODST update reverting the reflections change that was in the flight, and is due to whatever 343I did to make visor colors work on the old visor style.
