Dont get me wrong, Glyph, I know this is incredibly dangerous stuff, and I dont want to use it in our sector.<br/><br/>But I know that the tyranids are horribly overwhelming the eastern fringes of the galaxy and I think if this stuff kills 'nids, it could tip the favor back to the local galaxy residents. We kill the hive ships, we dont have to worry so much about planets. even then, if the planet is overrun we can scorch the rock with this stuff -and- kill what nids are still alive on the surface. (there is a short fiction in the 'nid codex about using vortex and nuclear fire on an overrun planet. Just scorched the planet. rippers and various smaller 'nids survived to be picked back up by the hive ships.)
