ReticleSpot and DefaultProjectile
The green bullet color makes them easier to see at a distance (even when on grass) while preserving the 3D-suggestion, I tried other colors such as yellow, red, pink and orange but the green bullet seemed better. Please keep in mind that this was while wanting to preserve the 3D-effect, if not yellow would be quite equal with green.
I also recreated a reticleSpot that @uré once gave me, its impressive compared to the old one. (You can see it very clearly at the ammo-gate in the 2nd screenshot).


If you want the files just give me a shout (read: pm) in case they are popular I will upload them on the interwebz.
Advanced Radar
I have developed a more advanced radar that you can read all about on this topic.

If you have ideas on other stuff that can be improved or want to suggest different colors please post in this thread.
