That depends which game you mean: Halo Combat Evolved, Halo 2, Halo 3, Halo 3: ODST, Halo Wars and Halo Wars were all made by Bungie, but they sold to 343 Industries last year. So far, 343 have only released Halo Combat Evolved Anniversary, which is a remestering of the very first Halo game, but Halo 4 is coming out this year, which 343 said will be the beginning of a brand new Halo trilogy.
Year 17
Halo 3 has been out for ages now. the newest is halo ODST and halo reach is set to be out next year 2010
Halo Wars was made in 2009, along with Halo 3 ODST
2007, shortly after Halo 2 PC was released earlier in the year
No only for the xbox (the first 2 are made for the xbox when halo odst, halo 3 , and halo reach are for the xbox 360)
Halo 3 will not be able to get for PC because Microsoft stopped working with bungie cause bungie tryed to buy Microsoft abd made them made so no halo 3 for PC.
There are two video consoles that the Halo games can be played on. These include Xbox and Xbox 360. Halo 1 and 2 were both made for the Xbox. Halo 3, Halo Wars, and Halo 3:ODST, and Halo:Reach, and Halo 4 were all made for the Xbox 360.
