Turncoats (2005)

From the publisher's website: Turncoats is a game of espionage where allegiances can shift at any time during conflict. Players must outsmart their opponent and manipulate the neutral force (which both players have control over) to win. This fast-paced game combines strategy, luck and ingenuity to create a game that is fun and intriguing for people of all ages. The games concept is roughly based on the idea of a military conflict where two warring factions must manage the effect of a third force which can be influenced by either side. The French and Indian war is an example of a conflict similar to what players will encounter in Turncoats.
