About Semper Fidelis Alliance, from BoardGameGeek:

Semper Fidelis Alliance is a science fiction game that uses miniature figures and incorporates mathematical calculations, artistic painting, and the creation of objects with dioramas, models, or 3D prints. It is not affiliated with any specific figure manufacturer; rather, it aims to promote all kinds of dioramas, models, and collectible figures, as well as providing a recreational activity without electronic devices, an alternative or complement to other forms of play. Players collaborate against imaginary, fictional beings such as zombies, aliens, demons, or extraterrestrials, with the freedom to use figures and dioramas from any brand or scale as they wish. Non-reflective grayscale interior, facilitates highlighting with fluorescent marker. -description from the designer
