When you need to call down the thunder to deal with those pesky biters, launch a rocket with an ion cannon into orbit and show the bugs who's boss.
NEW +3 technologies: Area Fire and Ion Cannon Mk2
Enabling the option makes the research for the ion cannon not take space science, but yeah the wording of it is very unclear and I'll change it for the next release. Thanks!
Sorry to repost, however, it doesnt remove the space sciences, 0.6 redid the science tree and the ion cannon is locked behind 3 space sciences. See image: https://imgur.com/a/ShwwpSv
Thanks for the follow up, I cleaned up the research costs and the new version should work cleanly with SE 0.6. With Early Research turned on the ion cannon should cost only up to the new Rocket Science, and auto-targeting should cost up to basic Space Science
