At UK Games Expo 2014, which opened at the end of May 2014, Modiphius Entertainment announced that it was working with designer Matt Leacock to release a co-operative board game in Q4 2015 based on the Thunderbirds television series, with 2015 being that show's 50th anniversary. Little has been said about the Thunderbirds game other than it being co-operative. In a press release from Modiphius, Leacock is quoted as follows:
I've had a great time immersing myself in the world of Thunderbirds, learning all about the Tracy family, Lady Penelope, and all their wonderful gear. This game will give players the chance to see how they would perform in the role of the Tracys. Will they be able to anticipate global disasters and complete impossible rescue missions? This game will test each player's nerve, logistical sense, and mettle. It'll tell you if you could be a Tracy!
UK game site No Pun Included recorded the announcement at the UK Games Expo and spoke with Leacock afterward:
