Publisher's blurb:
You've built your custom mecha, now arm it with its own custom weapons! Big Guns and Blazing Swords expands on the mecha construction rules found in Mechasys, allowing you to create your own weapons. Starting with basic ranged or close quarter attacks, players can add in styles to change the attack to energy blades, beam attacks, or missile launchers. Enhance those weapons further by applying traits that improve damage and range, and add item qualities. With over a million possible combinations, players can create virtually any weapon for their mecha!
In addition to the rules explaining how to customize your weapons, there is also a form fillable Weapon Designer sheet with self-calculating fields to make the process that much easier.
