Theres a poll of sorts going on and Planet AvP, pitting both our SP and MP parts of LAST ONE OUT and Colonial Marines:Online against each other. Multiplayer seems to be having a sizable lead. If you guys feel so inclined, go vote, lets us know what part of the project you are waiting for. Personally I think highly of them both, but that's just me ;p
Its in the right column just down from the top of the page.
