Iris perhaps is the biggest TDM city mission topping even Painter's Wife and I'm no joking. You can spend hours and even dozens of hours just scouring in the streets and houses of this mission. If you like city missions you would love this one.
If you like missions with unique and eerie atmosphere you owe yourself to play this mission. There' s a lot to do and to find in here in Iris. I would say without hesitation that it is one of the most ambitious debuts in the history of Thief FMs.

As it is the common thing with Connections contest missions it is loaded with custom assets and effects. I don' t want to speak much about it though.

On the other hand, the mission is not flawless. My biggest nitpick is that lots of compartments are empty and devoid from challenge aside from platformer aspect that somehow undermines the impression. Perhaps the mission is too big and convoluted though it could be just me. Perhaps it's more with my preferences: I like smaller and more focused missions. That' s why I like Hazard Pay from the same contest a bit more. But if a) sprawling city missions with b) surrealistic and dreamlike feeling about the world are your thing, Iris is what you are looking for. It' very well made debut and damn good mission on its own.
