One of the most anticipated computer games of the year, Half-Life 2, is seeing the light of day in November.
Half-Life 2 has been years in the making
The game is due to go on sale worldwide on 16 November, its publisher Vivendi has announced.
As well as appearing in the shops, the title will also be available to download over the internet direct from the game's makers, Valve.
Half-Life 2 is the follow-up to one of the most lauded games ever and its release has been repeatedly delayed.
Since its 1998 launch, Half-Life and its various add-on packs, such as Counter-Strike, have sold more than eight million copies worldwide, according to Valve.

The game will also come with the online multi-player shooter, Counter-Strike: Source.
Fans have already been able to get a taste of the online game, buying it direct from the game's makers Valve using a proprietary digital distribution system called Steam.
Valve has been letting members of its online Steam community get hold of encrypted copies of Half-Life 2 over the internet.
It means thousands of people already have the game on their hard drives, but it is locked.
When officially launched, Valve will release the codes to access the encrypted files and start playing immediately.
"It's difficult to say how much of an affect online Steam distribution might have on retail sales at this point in time," said Mr Pierce.
"One would expect sales via Steam to be considerable in territories like the US where broadband penetration is high.
"But then there's the question of collectability. Many gamers will always prefer to have their own boxed copy, complete with discs and manual, even if that requires a trip to
