It's 1942. While World War II rages on, the Nazis are closing in on the lost city that contains Brahmashiras, an all-powerful weapon bestowed to an ancient king by Hindu gods. You are Colonel Grom, the only person capable of stopping them.

Grom is a simplified RPG with real-time battles that are tightly woven into its intricate and non-linear plotline. The player commands a squad of soldiers whose actions are determined by the game's AI. Outcomes of the real-time battles are determined by statistics rather than reflexes. Grom strives to recapture some of the feel of point-and-click adventures while following an RPG-style, character-focused plotline.
