Tech Infantry is a fan-created Tabletop RPG that is sort of an expansion pack to the Old World of Darkness games published by White Wolf Publishing. It originally used the basic game mechanics, backstory, and rules of the original World Of Darkness... but was set in a 21st century world that borrowed just as heavily from Starship Troopers by Robert A. Heinlein and Armor by John Steakley. So you end up with werewolves, Mages, and Vampire Ghouls in Powered Armor fighting Giant Alien Bugs In Space!
