Halo 3 coming for PC it’s a recurrent rumor. A dream for many. Master Chief with 16x AA, Cortana at 1080p. Well, that’s quite a thing.

Steam Registry was playing again its role in this affair last month, but this time we have a new variable: AMD Catalyst Drivers.

The new Beta version of the drivers for AMD/Radeon graphic cards are listing Halo3.exe in its code. Remember, this drivers have a database where many games that can be “tweaked” with many improvements or custom settings are shown.

This is the code we are talking about:

Microsoft’s policy about Halo for PC it’s been quite… peculiar. They have always decided to publish the games with a considerable delay. Halo 3 was released for Xbox 360 back in 2007.

Do people really want Halo that much? Do they want Halo 3 for PC six years after its original launch?

If it has new achievments I'll get it, if not then I'll stick to the 360 version.

Interesting. There was leak about two months ago that said the HALO-series was coming to PC, but MS denied it and now another source says it is coming.

i hope this is true, i just found out that halo CE was actually on PC. im going to get it. was halo 2 released on pc btw?

Yes: 

holy fuck this is awesome! i always wanted to play halo but one game was never worth getting an xbox for me. i hope halo 3 is released on PC as well

Well, my guess is that with the next-generation and stuff like Gaikai, OnLive and given the fact that both nextgen-consoles are PCs I think that in a few years you can play what you want, no matter which console you got ;) For example, I am looking forward to play Uncharted on a non-Sony-platform ;)

well my internet connection SUCKS. i have limited download space (just 20 GB a month) so i wont be using gaikai anytime soon. its also the reason im not a PS+ member. but we will have to wait and see how exclusives and game streaming becomes in the future. 

My connection is quite good and I have no limit plus a very good latency to the first hop :) 

Sony has almost no option but to offer their Gaikai-Service for a lot of platforms to get as much money as possible. The servers, infrastructure and so on has to be paid and the audience to limit this only to Playstation-platform is way too small. An Android-client perhaps would be perfect :)

Game-streaming by now is limited to certain genres - no way you can play a racing-game or a shooter the same way as rendered on your console but games like uncharted will be easily playable.

But that's quite off-topic. Play Halo, it's great!

yeah, but this is a very deep topic, what devices should they offer it on and what content and what are the draw backs and perks. you should  make a thread about it

and yes i will play it hopefully. i like sci-fi shooters and halo has fantastic artwork. i always wanted to play it. here is hoping they make halo 3 on PC as well

Here is how this is going to work...

Halo 3 - xbox live release for Win 8, win RT, Xbox 360, Xbox 720, Windows Phone 8 simultaneous release. Buy one copy for 29.99...get access to it on all platforms. Multiplayer across platforms.

Guy can dream can't he?
