The Legendary Tactical Holographic Sight in Once Human is one of the game’s best high-tier weapon attachments, and you can add it to your arsenal for free by solving a riddle in Nalcott.

Once Human features numerous weapons which can be upgraded further by adding various mods and attachments. One of these attachments is the Tactical Holographic Sight, which gives you 2x zoom along with increased aiming speed, mobility, and stability to get those crisp headshots. The game doesn’t give you an exact location to get this attachment, so if want to add it to your weapon, we’ve got you covered.
