I'm sure this is a very stupid question but... how do you start TFTD?
I have both OpenXCOM (latest nightly), and OpenXCOM CE (latest), and both work fine for UFO but I have no clue how to start a game of TFTD. "New Game" / "New Battlescape" are just for UFO.
I've copied the TFTD files over to both.
In either of them the only place I can see any reference to TFTD is the mods drop-down.
Nothing in the log file suggesting any problems (or any explicit successes either; an entry saying "Successfully loaded data for UFO" / "...TFTD" would be useful for debugging incorrect installs).
And there's nothing on the wiki or getting started pages for these either about it.
What am I missing?
