Nightcall is interesting. It has the look and atmosphere to be a Top 5 location, but it’s dead last in terms of content. IOI should expand it and turn it into a proper mission like the rest, adding a creepy basement to the house, crumbling underground tunnels, and explorable shacks out in the dunes, full of lanterns that sway in the wind and the buried bodies of Reynard’s other victims, giving the level a real Splinter Cell meets Resident Evil vibe. I’d rather them put their time and effort into that than give us a bonus mission like The Icon, personally.
And, naturally, open it up to contract creation once there’s more to do there.
