Buy it from a PC games retailer
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
No. Bungie stopped producing Halo games for Pc after Halo 2
Halo 3 ODST is not for PC but Halo 1 and maybe Halo 2-3 are
Yes you can play both Halo: CE and Halo 2 multiplayer on PC.
Only Halo combat evolved and Halo 2 are on PC.
Halo for the PC has already come out, so has the halo 2. I know how to get Halo for the PC for FREE! Go toYutube and you'll see some ideas.
There are demos for Halo CE, Halo 2 PC and Halo Wars
there is no halo zero 2 there's halo zero halo PC (1) halo for vista (2) and halo 3
Halo 2 doesn't have one.
Yes, only HALO 1 and 2 though
Halo 2 for PC and cod2 for PC because both are old but both are rated game of the year.
The Xbox 360 does not recognize achievements nor have achievements for halo 2 for the xbox, halo 2 for the PC is different. Halo 2 on the PC has achievements and you CAN see them from your xbox if your searching his achievements. sorry
