Hi all, I'm from Vietnam. I have back here again :)
Today I'll send to you all there a modification for Half-Life engine. It's called Metahook, it's made by Csoldjb, its homepage: http://csodjb.blogspot.com/

How can use ?

3/ open hud+.txt in my pack, copy all text to your cstrike\sprites\hud.txt at last line, then save it
4/ Run UCP for join game. UCP will automatic load Metahook for you

Some console command need for you
mh_deathmsg_fillbg  // Turn on/off color on kill note
mh_deathmsg_toggle  // Turn on/off  on kill note
mh_killtip  // Turn on/off effect kill
mh_showkiller  // Turn on/off who killed you
mh_teammatename // Turn on/off teammate name
and more ...
