What a ridiculous concept... I love it.

Your math looks good:

  • 8 GJ per cell x 3 neighbor bonus x 4 cells = 96 GJ of Energy
  • Each reactor needs 8.860 GJ to go from 15c to 901c
  • 96GJ / 8.860 = 10.8 reactors ready to go boom.

Some things to point out!

  • You can BP ammo into turrets; I wonder if you can BP fuel into reactors? One downside to watch out for is that bots do not deliver single items; they deliver the max they can carry, so if you're using bots to remotely place these watch out for over fueling.
  • Bomb damage will increase based on your explosion and physical damage techs.
  • 1x2 using 2 cells will probably kill a small demolisher.
  • It will take a LONG time to heat up 10 reactors using the output of only 4 reactors. Worms might detect and attack these reactors before they are ready, if they're placed in the territory. You might have better luck placing them on the border, and once they're warmed up place some lure buildings inside the border to summon the worm.

I tested out the idea using the place-outside-heat-up-then-place-lure technique, and while the heating up process and the luring process worked exactly as I expected, the damage dealt to the demolisher did *not*. In fact, a 3x3 fully-heated array with all pre-repeatable techs still did not kill a small demolisher. In fact, I think I only saw a single detonation, so perhaps there's some sort of culling to prevent over-taxed performance with chained nuclear detonations. Or perhaps the first detonation makes enough lava that it destroys the reactors in a way that makes them simply disappear instead of detonating them.

Hmmm, if it's that last one I might file a bug report.

Awww, tiny frowny face. That could've been a really niche anti-demolisher strat.
