Brain-provoking time-travel RTS Achron, which Richard had a good old chat about here, has been out for a couple of months, but it's been lacking a demo for cautious, interested parties to have a play with before taking any kind of plunge. That all changes today with a demo that gives you a taste of the linearity-shattering multiplayer. Developers Hazardous say: "The recommended way to download the Achron Demo is via torrent," but "The demo is also available via direct download." Hooray!
I've also posted a video of some of the multiplayer action below.
