From the Core and the map shape (flat) with teh name, I had expected it to be raining Mass AoOs. There was instead an interesting script.
However, there is little strategy, although a small puzzle.
My solution:
Spoiler
Let there be Berthas, and no Snipers, and Digi-targeting Cannons. Let there be power and fire rate. Let there be range and rate upgrades. Let there be a few Mortars.
And then let there be a Nullifier.
If there was more than one threat, or if it were practical to lose, this would be more interesting. Interesting concept, though.
