Halo Combat Evolved
Accurate Reticles (v1)
This won't help me much, seeing as I suck so much from a year of modding, but anyway, this will help you for sure, if your not like me that is. I must say, my favourite of these is the Pistol Reticle. You used to always have to aim with the bottom
This is a reticle pack by Jackle, replacing the normal Halo PC or Halo trial reticles with ones that make it easier to aim accurately.
