what are kill marks? the symbol if u kill some1 for headshot, double kill, trippel and all that stuff
where are they located? in the crossfire folder, in rez / ui
do u get ban for them? no! cause it doesnt make u better like any hacks or idk and
they dont edit ur ram(=hacks)
how to install some that i downloaded? just put them into the folder and replace the other
what they are exactly? they are just like a "design"
its a .tga file, its like the same as bitmap but little diffrents i think like it can use
transparent
how to make ur own? use photoshop or paint.net like i do and just draw a own
