HOW CAN I PLAY ON-LINE HALF-LIFE. I BROKE THE ORIGINAL CD AND HAVE ONLY A BACK UP...

[uk_f.u.b.a.r]

right m8 if you have a back up install halflife then enter cd key
exit game
then update halflife to official patch v43/1.1.0.6 patch then you can play on line but
not offline
if you want to play counterstrike then u will have to install it and update to v1.1
the only prob is if your on 56k its gonna take along time m8 as the files are huge
better off buyin an pc gamers mag get it off disks

good luck m8 aka uk_fubar
