Is there any way for a Zerg player to take out Mass Thors? I was in a team game that got drug out and my random team mates were terrible. I managed to single handedly get to 6 expansions and wall in the other team. I had plenty of min/gas and kept a constant harass on all but the terran player. all of the sudden out came the fully upgraded mass thors. Must have been 15-20 of them. I sent in Ultralisks, hyrdas, broodlords, mutas. I literally would take my 7 hatcheries and que up my next army when the previous died. IN the end I had to base trade, and won b/c he ran out of buildings. Can a zerg player kill thors in mass?
I really think Ultras > Thors! Otherwise how about the Brood Lords? With the broodlings they send, its awesome raw power and the thors wont know where to shoot
mass immor- oh wait... zerg... counters to a terran unit... nah, sorry. They don't make those for zerg. A pure army of one type of unit isn't going to work, and straight up 200/200 armies hitting each other isn't gonna work well either. Zerg does have a bit of a disadvantage in unit strength especially against thors. Mass ultras or brood lords aren't gonna work. Thors are simply stronger than ultras and brood lords are too fragile. Now, if you had a combo of a few tanker ultras, a few brood lords for the extra damage and obnoxious broodlings, and infestors to grab a handful of the thors, you might be good to go. maybe even weaken his army before the fight. if you see his army and know where he is headed, have banelings ready to burrow in his path and use them like mines. also keep flanking in mind. if you attack him from the front with ultras and lings (maybe a few ranged units of your choice behind them) and hit him from the back with roaches and infestors (both able to tunnel while burrowed) he will have to direct his attack at one side or another or lose his strength.
Ultralisks and pretty much any of the Zerg fliers don't do well against Thors. Brood Lords are okay, but even with their attack range, they are still just inside the range for the Thor's AA attack. What I usually do is send in a couple dozen Zerglings to draw the Thor's fire, then use a small number of Corruptors to debuff the Thors before sending in Mutalisks. Between the Zerglings acting as meat shields and the increased damage from the Corruptor, My Mutalisks usually make short work of an advancing Thor army.
Use a few Corruptors to let them take 25% extra damage, while your Ultralisks engage them. Problem solved. Other then that, letting any player mass powerful units like that is just asking for trouble. If a player manages to mass that many, then it's a problem of you not harassing enough and picking them off before they reach a critical mass. It's like the time I read here: "the guy had like 20 Carriers, it's so unstoppable!" Well of course it is, but you shouldn't let him get that many in the first place. ^^ And if all else fails, a crapload of upgraded Zerglings. He might be able to one shot them, but they'll run and attack so fast, that you'll take out a couple Thors each wave. Very mineral heavy, but with that many expos it should be no problem. Edit: damn, Kaaraa beat me to it. ^^
A possible counter for Thors may be like Prawn suggested with banelings but I would add the swarm of lings to go with it cause they can totally surround the Thor and attack it from many sides. The Thor's focus should be on the bane's leaving the lings more time to chew em up.
Lots of zerglings my normal solution to thors, but the question you should be asking yourself is this.... How the hell did hell get the resources to fully upgrade a huge army of thors from? Its not like terrans have great scouting ablities and you have a lack of units well designed to sabotarge. As zerg you should slowly strangle his forces, limit his growth and stop him getting a serous force together in the first place.
The major counters are infestors and brood lords. Anyone who says thors beat brood lords is dead wrong, brood lords are armored and take years for thors to kill. Infestors can neural parasite and then, if they were unfortunate enough to research 150mm cannons, have the rest of their thors stunned and destroyed.
brood lords beat thors but it is really not that hard to spit out 5-10 vikings late game, ultras+lings beat thors in small numbers but once there is a ball of thors and the ones in the middle can fire all the zerg melee units thors are almost invincible, burrowing the the ultras helps but not much, infesors would work except now neural parasite only lasts a short time and has a really short range so yeah...
