Antenna is a Third location found in Dying Light.
Antenna acts as a third map in the game, but has no main hub, such as The Tower for the Slums. However, The map size is very small when compared to Slums and Old Town. The only significant on goings for this location are the Quests (Final Main Story Quest) and (Final Side Quest for Tolga and Fatin).
The blueprint for Airstrike can also be found in this area, as well as a Plants vs. Zombies easter egg.
