Rules v1.2.4

Jovian Wars

Jovian Wars is a near future tactical space battle game played on a tabletop with miniatures and dice. Each player builds a fleet of models and then commands it in a tactical game by maneuvering around the battlefield, attacking enemy ships, and attempting to defeat their opponent by completing scenario mission objectives to gain victory points.

What Jovian Wars is not: a physics simulator. It is first and foremost a competitive wargame inspired by space opera and mecha animation.

When possible, aspects of physics inform the mechanics, but the primary focus of these rules is to create a fun and immersive game that can be played in 3-4 hours competitively.

To that end, Jovian Wars is played on a 2D surface, typically a 48" x 48" table. The experience of playing in 3D is represented in the rules in many aspects such as models being able to move and shoot past/through each other.

This game includes large capital ships and small space fighters including Exo-Armors (Space Mecha) battling it out in a future Earth solar system wide conflict. The Scale of the Exo-Armor and Fighter models are 1/1000. Capital Ship models are approximately 1/4000 scale. Note that this is an approximation and is not exact.

Jovian Wars will begin with three major factions: Earth/Moon (CEGA), Venusian, and eponymous Jovians. The Mercury, Mars Democratic, Mars Free Republic, Asteroid Belt Miners/Pirates/Nomads, Saturnians, Kuiper Belters will come at a later date.
