Ruins & Radiations: House Rules for a S&W/LL Science Fantasy Campaign

After I've dropped several projects of mine, finally I've collected the House Rules I've used in Swords&Wizardry my science-fantasy campaign (but you can easily use them with Labyrinth Lord).

Basically that's what they do:

• They allow you to make custom classes (like Thief, Bard or Paladin) starting from the six core classes (Fighter, Magic User, Cleric, Halfling, Dwarf and Elf)
• They use a roll-under resolution for combat (with a descending Armor Class), skills and saving throws
• There's a revised system, still pseudo-vancian (same old spell slots) but with a more talislantan-style approach (spells created on the fly and possible mishaps)

Enjoy it. ^_^
