A test version of a prospective set of WW1 rules titled "Fight the Kaiser!" is available. It is not quite enough to put on Wargame Vault, so for now you will have to email me for a copy or you can download it from Discord. Email is at nordicweaselgames@icloud.com 

The rules are aimed at roughly platoon level and the test version so far only covers 1914 (to have a confined area to test the core game mechanics). 

Drop me a line and you can help test it out.
