The AI misbehavior is an issue I can't fully resolve, as the in-game editor doesn't support rebuilding the navmesh based on custom prop setups, which is essential for AI navigation. However, I can adjust some AI to idle to reduce the misbehavior, and I'll work on refining the cover setups to improve movement flow. Thanks again for the feedback!

Just too many routes, with lack to provide sufficient cover after clearing partial spaces to next chokepoint. So, "overwhelming" might not be the right word for it. AI gets stuck beneath plane on fence (at the rise-up cargo container).

Futhermore I experienced dropping off of AI from highgrounds (especially the "outpost building" with the sandbags on top).

Just as an Idea, maybe something like biuldings at either end (maybe windowed with top-access to your desire), barrels or low covers in certain different sized areas
Similar build at bottom but not mirrowed
Integrated truck(s) as cover
ramps to airplane/highground less dense/common.
Just an idea. Easy to say, as I have no clue to design something myself, so dont take i too seriously ;-) . Appreciate your work and effort!

Thank you for the feedback. The goal is to create multiple alley-style approaches to the plane while expanding the short to mid-range shooting engagement space to provide a different experience from the original. I've implemented special props setups to differentiate the spawn points and various routes to avoid the "maze" feeling you mentioned. So can you elaborate on that a little bit? Do the routes all seem similar to you or there are just too many routes to the plane, making it a bit overwhelming? As for the inappropriate prop usage that felt off, that can definitely be worked on to enhance the overall rationality.

Sry to say: I appreciate the work you put into this and you have put up some effort into making this. It's just not my type of map-design.

More detail on what I did not like here: Feels like a maze with a trapped Plane inside it, weird object-placements (like fences used as ramps which is somehow cool but ruins the flow, waay to many approachings to the plane)
I somehow would rather have some sort of Squared layout with some few obstacles in it with the Plane in the center maybe?

Keep it up. For me: less would be better.
