All of the robot capsules (Defender, Distractor, Destroyer capsules) don't see much use due to their implementation in the base game. Maybe some alternative recipes and maybe a Military Science pack(s) that use them could make them a little less forgotten.

Oh sure, will be added in a future update. Thanks for the suggestion :D

I should have put this discussion on Space Age Galore, I've thought of some recipe ideas that may or may not work using Space Age items.

All Capsules could use a similar recipe to that of the "Sentient Logistic/Construction robot" recipe where Pentapod eggs are used in the crafting recipe. The use of ether Discharge defense equipment or Tesla ammo would fit with the Destroyer capsules as it does the same electric damage as the previous two items.

As for a science pack maybe something that uses both Destroyers and Cluster grenade for Military science?
Funny enough part of me feels like the Destroyers and other combat drones might be able to work for Chemical and/or Utility science.
I don't know why it just feels right for some reason. Same thing goes for the Poison and Slowdown capsules.

It might be worth throwing the Capture bot in this list too but as it is it far out shines the capsules and combat robots so might not be necessary.

Oo~ nice ideas! Some of them will be included in the next update, but for others I will need to look a bit more into it. (Also, sentient combat capsules sound REALLY EVIL, I like it lol.)
