Really cool of you guys to ask and indeed answer all of the unresolved issues and mysteries about TCP. It's amazing how much enthusiasm has been created about a never-to-be-completed mod only supplying the first stage of its initially envisioned state. Although playing it through, it's easy to see why!
What I'd really like to know (and this was asked earlier but not answered): what exactly was up with the hidden chess pawns in the base? Was it planned for them to have some purpose in the game?
And what other Apollo Mods did you have planned for use (or what ideas for them had you come up with). Anything radically different to the abilities that the Deus Ex augs granted you?
