normal 40k escalation i see

I find the escalation choice extra funny cause in canon the Tyranids would NOT run that fade. Necrons are the single WORST enemy they can go against.

- Can't absorb them for biomass or get adaptations out of them cause they're all mechanical.
- Gauss weaponry disintegrates matter so the Hive Mind's taking permanent losses for every killed bioform.
- "Shadow In The Warp" is worthless cause the Necrons are anti-Warp themselves, and can in turn shut down the Tyranids' psykers.

They've got everything to lose and nothing to gain fighting the Necrons, basically.
