I’ve been playing on Veteran difficulty and Lairs have been a pain in the bum every time. Last night I restarted many times in order to complete it, with 1 death (always a berserker lol…).
The first lair I took down had at least 5 active Sirens and I was lucky enough to have a unit that could not be mind controlled to deal with them. I tried to deal with them from range but they used cover too well.
The lair last night had 2 Chiron and eventually I worked out I could just use war cry to negate their ability to launch bombs. I used incendiary grenades to burn them + hold back the tides but in the end I had to send my heavy to solo-kill the lair as I could not win just by killing as I didn’t kill fast enough.
It’s annoying that you cannot prevent Sirens from using MC even after their head is disabled and that it doesn’t cancel a current mind control that’s in progress. My units will usually run over and use their own medikit to heal the Siren as well lol…
I don’t know if it was successful tactics or I just got lucky from last night’s lair. The heavy I sent solo was mostly ignored, with just 1 of the 2 Chiron launching bombs at him (missing the hvy and doing dmg to the hatchery). It only took 2 rounds for the hvy to kill it too so “distract-and-solo” may by my new anti-lair tactic. I have no idea why a Siren didn’t head towards him either - I don’t think the path was blocked and I knew at least a few were around.
