No. It was only ported to the PlayStation 2 for home consoles.
yes
No
You can't
Currently Half Life 2 is available on Xbox 360 format for purchase on many online stores. The cheapest price online is on Ebay for $6.99. You can also purchase it in a bundle called Orange Box that includes Half Life 2, Portal, and Team Fortress 2 for $16.96 on the Xbox 360.
No it is a Xbox PC game
As of now, unless you have access to a modded xbox 360, and figure out a way to move the map files in half life 2 into the place where the portal map files are, then no.
Y is there a xbox 360 garrys mod
Some games for original xbox do not work on the Xbox360. You can find a list of games that do work at www.xbox.com
yes the only half life game that the orange dosent have is the orignal as it was only created for the PC when it was made and it is untransferable to any games console
In short, yes it can (if you mean Half-Life 2. The original Half-Life was not released on the Xbox). You'd be better off though if you got a copy of Orange Box for the 360. I has HL 2, its two expansions, Team Fortress 2, and Portal. All on one disk. It currently sells for $20 new, but can be had for cheaper used.
No, and if it was possible what would be the point of buying and Xbox 360 anyways, besides the point of live? You can play a lot of regular Xbox games on the Xbox 360.
Is xbox live possible with a dongle
