Many sequences feature optional secondary objectives or specific challenges that, when completed, award bonus points and contribute to your overall mission rank. These can range from rescuing civilians, collecting specific items, or performing a mission without killing anyone (non-lethal run) or without being detected (ghost run). These challenges are often displayed at the beginning of a sequence or can be viewed in the pause menu. Attempting these challenges adds significant replayability and encourages mastery of the game's mechanics. For example, a 'No Kill' challenge might require you to use non-lethal takedowns and distractions exclusively, while a 'Ghost' challenge demands perfect stealth. Successfully completing these often unlocks unique upgrades or cosmetic items for your Assassin. Always check the mission brief for any optional objectives before starting a sequence.
