Simple mod that allows user to customize Spidertron's weapon slots. Optionally adds a fifth weapon slot, and dynamically modifies spidertron recipe to require the new weapons.
In case the Factorio Standard Library has not yet been updated to 2.0 by the time Space Age releases, all you have to do to make it work with this mod is to unzip the stdlib mod, then edit the info.json and change "factorio_version" to 2.0
