A short Codex-operated desktop-browser test of the updated Five Nights opening: I queued a sandbag wall, wire, a trench and a fighting position, then left Build mode and saw the work detail start building. Pausing while planning and showing the completion times in the works queue made the distinction between placing an order and finishing it clear.
One specific terminology snag: the tutorial asks for a “Fighting position”, but the Positions button says “HOLE”. The next order asks for an “M60 position”, while its button says “M60 PIT”. The tooltips explain the mapping, but matching the order text to the visible button labels would remove that extra lookup.
I stopped during first-day construction, so this does not establish whether the defenses hold the first night or whether the campaign stays engaging. I’m working on Turnfeed Kingdoms and dealing with similar order/result clarity; I’d be happy to compare a short opening if that is useful to you.
