Marty59 How do I play with a friend who doesn't have plutonium

[Dss0]

Adam_Nizami you can't, plutonium is separate from steam.

[Adam_Nizami]

is there anyway to launch my copy of the game through steam??

[Dss0]

Adam_Nizami well if you own bo2 on steam just launch it via steam. You can't do that without owning the game tho.
It would prolly be easiest if your friend installed pluto.
