User blog comment:Ziebro/Result of Necrons vs Tyranids/@comment-28917471-20130828185316

It's a vey, very, very easy question. When the Tyranids fight their enemies, they expect to gain some Bio-mass. If the Tyranids would face the Necrons, the would gain no Bio-mass, thus, no chance to reproduce thier casualties. Knowing what Necrons can do with their techs, like rebuilding themself, and destroying their enemies with their Tesla weapons, I would say that the Tyranids will be defeated in no time.
