Halo Wars Platnium Hits question

[Fighterspledge]

Is the included DLC on a separate disc like Fallout 3 GOTY and Oblivion GOTY editions? Just wondering if you can get the DLC on your HD since I already have the OG copy of Halo Wars on hand. Want to pick this up on Amazon but I want to figure out if I need 1 or 2 copies for boosting gamerscore.

Is it confirmed that the PH version of Halo Wars has the DLC on it?

[Fighterspledge]

Yeah it says so on the box, all the DLC. I'm wondering how it is used. Is it still required to be installed onto the HD or does it run straight off the disc?

I could have sworn that it doesn't include the DLC. The UK hits version does though.
