A very good mod indeed, one of the best I have played. It is incredibly well-designed, and the idea for two separate endings is something great which I have not seen in a mod before.
A couple of minor annoyances throughout was that the constant reliance on keeping two scientists alive became frustrating after a while, and I also found the AI's path-finding untrustworthy at times.
But on the whole, a very excellent mod. Definitely sets the standard for mods made everywhere.
