Span missions

Am I to assume each one has one correct way? Every thing I try ends in failure, no matter how good my defenses are. And what's with the creep suddenly bursting from the ground at specific points, like next to my walls??

Span Experiments are the maps that were used in development for CW4, they have huge variation in difficulty, but they should all have multiple solutions.

Some Span Experiments maps have custom behaviours that are not explained, and from your post you might be on the map 'Shaka'. How that map works is there is a unit called an "Impeller" in the southeast, it sends any creeper or anticreeper underneath itself to the Hold Base in the southwest.

This might not be obvious, but there's also the chance that somewhere on the other side of your base some site (such as a totem) is attempting to pull an egg towards itself. So, as the tiny egg moves across the map, maybe one of your snipers targets it and shoots it, causing it to unload its creeper. Now, because the egg is tiny and moving along a vector you are not visually scanning, and because you place your snipers in certain positions where they can hit a target flanking across a different line than you anticipated, they happen to have fired as the egg was crossing near your wall. If this is too obvious and you've already disregarded that, my apologies.

I have had some problems with my strategies in the span experiments, but I think one thing that really helped was learning how to balance my ability to match in-flow with out-flow and to anticipate when certain energy thresholds and limits and increases occur so that my build times and loading times hit at the right moments. You can't just pause, lay down an entire plot with lots of towers and pylons optimizing miners and refiners and ore sites and turrets and mortars and runways all in one go, then unpause and run with that. Well, you could, maybe doing so and then also manipulating when entire sections of your blueprint activate by using those appropriate toggles in the unit menus and grouping things.

In a sense, the whole thing is like figuring out how to turn a small business into a transnational corporation bent on criminal enterprise.
