Isotope - Back in time, baby Two teams fight over a heavy water production plant, by blowing up half of it. How do you blow up half of it, you ask? By dumping some australium down a pipe of course! Of course you can't actually dump it down there without getting yourself down there. Some of you may die, but that is a sacrifice I am willing to make. Developed with 2007 in mind, this map is linear, choke-heavy, quite small, and 'bad'. Truly a product of its time. Custom assets are used only when necessary, trying to stick with things you would have seen in maps of the time.
