I've been playing on map4 icemap for a while, and I've come to notice that my white reticule almost seamlessly blends in with the background colours so much that I have a hard time seeing it most of the time.

In any case, a quick fix for other people experiencing this problem would be modifying the aim_helper .png in texture.

My aim helper is a yellow dot, like in Men of War.
Open paint.net or photoshop or whatevr you use that isn't MS paint, put a large yellow dot with a soft brush (or however you wish to do it) in the center of a 32x32 image. Make sure the background is transparent. Save as a PNG-24 as aim_helper and replace the one in your media/textures directory.

Or use this one, in the attachments->

EDIT: Or are you talkinga bout the main crosshair? A simple solution would be to have a small outline around it...
EDIT2: I just made something quickly. I haven't played RwR in a while or tested it, but theoretically this should work.


EDIT: Oh, installed the new version, looks like it's already been fixed. Consider these alternative crosshairs then =)
