Crimson Dust Science Fiction Wargames Rules
Crimson Dust is a new set of science fiction wargames rules. The author writes:
Crimson Dust (not to be confused with Crimson Dusk) is a sci-fi skirmish game using mutliple D6 rolls to establish the results of shooting moving, etc. Its also a turnless game with players activating models or using a leader groups of models in sequence, being turnless means you can keep activating the same model whilst your opponent for example activates all of their models, as opposed to variations of ‘I go – you go’. This is significantly more detailed game than Crimson Dusk, and has very different mechanics, it been an very exciting project to work on. in addition we’ve been given permission to use some of the art of ‘Juddeski’ who is a young artist known on several forums, his artwork will come to decorate the internal pages of the rule book.
