Bastion/guardian elimination/spawn rates?

I’ve only seen like 3 in the past week. Anybody having the same issue or know a tactic that I’m not aware of?

Well, for one, you could check this wave pattern guide linked below out for the waves when Bastions or Guardians spawn :

And have a team comprised of five human players as it seems the game will spawn more big enemies accordingly. They’re now very unlikely to show up if you only have bots on the team.

Was helping my brother with this one tonight. Loaded up custom horde on wave 16 on intermediate/advanced and had them almost every round until end of wave 20.

Repeated this 3 or 4 times and he got 12-15 I think.
