I love your mod! and it made me do it an account here haha, please dont be mad, let me suggest:
-Changing the UNSC sniper rifle bullet decal to plasma damage.
-Sgt. Johnson model and UNSC Marines models shown in ¨Arriving on Halo¨ to those of Halo 3. Also changing the Marines who uses sniper rifle in ¨Arriving on Halo¨ to ODST model.
-Make both Rhino tank and the modified warthog have matching camo and to all the UNSC vehicles to more immersion. Warthog to have some sort of antena simulating radio.
-Warthog turret: more damage, less fire rating and meanner fire sound.
And I think that's all, If I can help you on something I know how to use paint.net hahaha, idk how you did this mod but if you tech me I can help you with these. Thank you in advance, brother! My favourite mod for Halo CE!
