Because it's taking me a lot longer than expected to release the final v5 patch for Demo 3, I'm going ahead and unleashing the current version on you poor, unfortunate souls. Demo 3 v4 is, for the most part, still perfectly complete and bug-free; the stuff in v5 is meant to knock out the last few issues (mostly netplay things) and add some minor improvements to a few of the maps and some major ones to the AI. But in the mean time, just go ahead and get v4, and then download the v5 patch once it's ready. The majority of the experience will be the same from v4 to v5.
