Buy it from a PC games retailer
Halo 3 ODST is not for PC but Halo 1 and maybe Halo 2-3 are
They are both good, but halo 1 for PC has great maps and you can make custom ones, but halo 2 has that feature too. i would recommend halo 2
Yes. but it is hard to come buy you can also get it online but if you do find it dont get surpriced only halo CE and halo 2 is on the pc
buy a playstation
to get combat evolved buy it to get custom edition get halo 1 for PC and download custom edtiion from download.com duuh lol :p --
you can play halo 1 combat evolved on PC but if you want to play halo2 and 3 you have to buy Xbox360
Yes you can. You can buy it! I'll suggest amazon.com
Yes, only HALO 1 and 2 though
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.
Sorry but you must have halo combat evolved for pc.
It is impossible on the Xbox but it can be used through maps in Halo Custom Edition(on PC). Halo Custom Edition is a freeware but it requires Halo PC which is not free.
