What sci-fi campaign can't use more guns?
Infinite Guns is a designed to let D20 Modern game masters generate entire new weapon systems with just a few random rolls. Inspired heavily by the "procedural generation" gun-creation system found in the videogame Borderlands, Infinite Guns is the perfect accessory to an Otherverse America or Psi-Watch campaign.
Want to build a unique shotgun for a Lifer sergeant? Need to quickly roll up some knock-off laser pistols used by Mung Thoy Than enforcers? Got a new alien race jockeying for position in Earth's criminal underground, and need to give their gun-thugs some unique weapons? This short PDF will help you do all that and more.
Infinite Guns is designed for a setting like those I've mentioned: conflict heavy, dominated by fiercely competing factions or species with vastly different tech levels. It works best in a setting where technology is a bit schizophrenic, where different cultures use dramatically different guns, and where energy weapons are as common as slug-throwers.
