How can I download the Multiplayer for HALO CE if I only downloaded the Campaign?

Downloaded the Campaign only for HALO CE, but now want to play co-op with a friend.
How do I downloaded the "multiplayer" option, that I didnt check mark in the beginning?
The option isnt showing up.

alternatively, right click the game in your steam library, then properties, and in DLC section, you can check mark the stuff you want installed, and steam will install it for you (i'm not sure what it does if there isn't enough room)

this option is for inside the game itself.
