I imagine this was no easy undertaking, the dynamic element on this map's compatibility with bot's capability for adaptation is apparent. The largest issues with the map are the navigation, but it's hard to do anything about that with how many situations the train behavior creates.
That said, playing fastener was an immensely satisfying experience. The whole combination of defending a traincar while simultaneously trying to clear waves and collect money seems chaotic, but it just works - works REALLY WELL.
The secondary support traincar ferrying bots was always a good twist and gave a lot of really fanatic yet fun moments.
My only other complaint would be that following losing the front it almost felt inevitable to be forced to hold nearly all the way back at spawn, this may just be because the bots would navigate and stack at the tower, making pushing back into the building a large ask.
I think from a class perspective it would be nice to see more packs at the front, I think there are no packs at all in the front warehouse, making engie strongly incentivized which is a shame.
Overall I hope you stick with working on the map post competition, and if you do I'm looking forward to where it goes.
i'll add more resources to the warehouse area - thank you for your feedback!
