A Call to Arms is a series of space combat wargames from Mongoose Publishing. The first edition won the 2004 Gamer's Choice award at Origins. The series used the Babylon 5 license from its start until Mongoose shut down its miniature production line in 2008 and later lost the license. In 2010 Mongoose announced A Call to Arms was returning for a third edition using the Fading Suns RPG setting. This edition was subtitled Noble Armada and was released in February 2011. In June 2011, Mongoose announced another version, Star Fleet, set in the Star Fleet Universe. This edition launched in November.
A Call to Arms is noted for streamlined, fast-playing rules and providing multiple races to choose from. Throughout the series' lifetime, Mongoose supported it between books with articles in their monthly online magazine "Signs & Portents."
