Disclaimer these are no gameplay adjustments, only visual adjustments.
I love Halo (me joinging this forum is exhibit A)
But there are some things which could bring more immersion into the game.
As we all know Halo has a really great first person view, you can see your legs, arms, armor etc.
But as we all know the FPS perspective is a different model than your third person model. I suggest just one model, even Duke Nukem forever had this and somehow it's really immersive.
The other thing is damage, I would love to see the impact my weapons make on enemies and not just on walls. Not huge gory guts and such, but the amoudn of blood in CEA was just right. give them some blood textures on their bodies (marines have this in Halo 3 but the textures are static.)
Other things include battledamage, I would love to see my by spartan getting damaged up and still fighting.
If anyone else got some Ideas on effects and such.
Please comment below.
See you on the battlefield.
