The alliance of every major faction in the Galaxy even with chaos is pretty much impossible in a certain extent, the imperium will not join forces with chaos end of story, although it is quite possible for the imperium, tau, eldar, orks and necrons (last two indirectly)

With exterminatus, deadly technology, and the might of these factions, but isn't that enough?(I'm throwing a curve ball again) Again the Tyranids already consumed another Galaxy or two before coming to the Milky Way, a Galaxy worth of biomass and evolution traits and no one knows how many galaxies they already consumed that will bear down eventually in this Galaxy.

the only way I imagine it is to destroy the hive mind directly destroy the link that made them Tyranids, without the hive mind why would you destroy the swarm if you can just watch them destroy themselves? Instead of injuring the body why not the head?

Their a swarm of different tyranid species like ants wage war against other ant colonies and species. But their is a problem.

How?
