I didn't even execute it properly and I massacred.
factory /reactor ASAP
flip flop, start hellions
factory number 2
pull SCVs from gas @50 (I messed that up in the replay)
flip flop, more hellions
It's honestly just 2 factories worth of reactor hellions attacking. It's that simple. It doesn't have to be allin, but 2 reactors worth of hellions is a lot of minerals and it's hard to fit in a CC at a reasonable time, so I just cut workers and finish him.
He harassed my worker a bit and my stuff was a little late. He sees reactor hellions, goes for 2 queens and an evo chamber wall off while getting roaches.
I harass the queen for a bit, break the wall, and charge in. I kill 90% of his workers the moment I break through.
He gets a few roaches and a spine and completes the wall off. I engage the roaches and kill them, followed by breaking down an evo chamber and finishing the game.
I haven't tried it very much against protoss, but it's very strong there as well if you catch them off guard. Hellions absolutely shred zealots and sentries.
I don't usually all-in, but I was messing around in team games and ended up making this build, and then realized it would be really strong in 1v1s too. So try it out, I want some more reviews on it.
I've been messing around with it on beta too, leaving 1 SCV on gas so I can throw a few widow mines in there. Use the hellions to cover for the mines planting themselves in the mineral line, and using the hellions to bait roaches and such onto the mines.
I'm growing increasingly convinced it's borderline overpowered.
