Liberal and progressive Christian groups say a new computer game in which players must either convert or kill non-Christians is the wrong gift to give this holiday season and that Wal-Mart, a major video game retailer, should yank it off its shelves.

Left Behind Games' president, Jeffrey Frichner, says the game actually is pacifist because players lose "spirit points" every time they gun down nonbelievers rather than convert them. They can earn spirit points again by having their character pray.

"You are fighting a defensive battle in the game," Frichner, whose previous company produced Bible software, said of combatting the Antichrist. "You are a sort of a freedom fighter."
