This download is a self extracting installer including all you need to host and play Exterminatus - Rival Species 2. Two Species: Humans and Tyranids. Thirteen distinct classes, each with their own weapons. Nine maps from the 41st millennium, each with their own missions and objectives. Alpha 8.55 features a new method of connecting to EX servers as a workaround for the server browser issue. Although this isn't as automated as I would like it should make it more convenient to connect to a server.
