Trench Foot is the predecessor of Trench Club. The game was only published in a smaller print run and only in Germany. Trench Club is the improved version – so if you are looking for a game to play, go for Trench Club. If you are a collector, though, you might want to grab yourself one of the last copies of the original game.
Trench Foot game has gone through a long development cycle and has been excessively tested for great gameplay. I started working on this game more than 10 years ago and have iterated on the gameplay and design since.
