Campaign Advice for Sven Hard

[garrettcarrott]

I am losing my mind. I have gotten two stars on every single other boss in this campaign, and yet I still cannot understand how you are supposed to defeat sven. Does anyone have any advice?

He always sends on boss and mini-boss waves (5, 10, 15, 20, 21), so build to counter those waves.

Consider picking Lock-In for an anti-boss unit like Ranger or Berserker.

You can also try to break him 1 wave before each boss wave. For example, if you send hard on waves 9 and 14 against him, he'll likely leak.
