EVA_MaD and MuTe used to be UFOs. At this time, we´re not able to explain why, and even agent Mulder called us wackos for claiming such a thing. Scully on the other hand, threw the demo back at us, calling us names and speaking of wasted time. It was cruel.
And just because the moonlanding may have been fake, and due to the fact that Roswell aliens didn´t play TA when found, there´s only one conclusion:
UFOs may or may not be valid in TA games, but should stick to X-Files.
If you read the text above, know that it makes more sense then this game.
