I came accross this build last night, i poorly scouted it too so by the time i reacted he had a decent thor count, scouted the helions and on scrap station was just expecting him to helion drop then tank/rine push through the rocks and cut my bases apart. but he didnt instead he kept harassing and i kept droning, and when i realised what was going on i wasnt ready.

I thought about the game after and realised due to not seeing this strat for many months, that in the past i never came up with a solid counter, more a counter to stop him getting the high thor count.

I responded poorly and dished out roachs, with claws and burrow at least but yeah, and mutas of all things, /Facepalm. im wondering how other zergs deal with it if you failed to scout it coming.
i was thinking roaches to tank, hydras(Maybe) a few banes but NP Infestors to win the fight.
Logic here is Roach to tank the helion damage. banes to kill the helions and NP the thors to take out maruaders and the hydras to help the dps on the maruaders. It just feels way to gas heavy to manage.

(Other option i guess is nydus around the joint and take advantage of the slow moving thors by attacking scvs every time he pushes)
