Caught in a bitter feud between spiteful gods, Invictus demands that players fight for more than just their lives. They must enlist the mightiest heroes in an epic struggle to attain an eternal seat atop Olympus. Eliminating the need to gather resources or manage research trees, Invictus focuses the player upon carefully shaping a war party and balancing their strengths and weaknesses, because these warriors will be carried over from mission to mission. The player will choose from over 30 distinct units, each with a unique ability, like Gorgons turning flesh to stone or a Harpy's poisonous claws. The player recruits new units from those they have encountered in their journeys. Ten legendary heroes are at the player's beck and call, each of whom is a super-human warrior who can call upon the gods for special powers.
