Title: The Time Traders
Description: DRAFTED INTO THE ARMY OF TIME

Intelligence agents have uncovered something which seems beyond belief, but the evidence is incontrovertible: the USAs greatest adversary on the world stage is sending its agents back through time! And someone or something unknown to our history is presenting them with technologies -- and weapons -- far beyond our most advanced science. We have only one option: create time-transfer technology ourselves, find the opposition's ancient source...and take it down.
