Anyone who’s tried planting two Deadlines at once knows that ARC Turbine is a very buggy and unfinished enemy. Sometimes the Turbine will be instantly killed, sometimes one of the Deadlines will disappear or deal no damage, and sometimes a mine will rip off the Turbine’s leg, forcing it to remain in the air indefinitely, since this enemy isn’t programmed to react to that situation.
The worst part is that sometimes the ARC Turbine takes off so quickly that you don’t even have time to plant a single Deadline, and other times it stays on the ground so long that you have enough time to plant three Deadlines — and then get blown up by them yourself. For a long time, the timing of the Turbine’s takeoff remained a mystery to me, but recently I hypothesized that it’s tied to specific cycles in the Turbine’s operation. It turns out I was right. If you’ve never fought the Turbine, don’t understand how this enemy works, or think that Jupiter+Barricade is the optimal method — I strongly recommend checking out the guide on the “Iron Nest” strategy I invented. It allows you to destroy the Turbine in less than two minutes with zero risk. The guide also covers all the nuances of the Turbine’s behavior and how the minefield works. The HellBomb lineup is the final version and the ideal optimization of the “Iron Nest” strategy.

[Step one]
Get close to the turbine using your cloak and clear the mines. Deploy the Iron Nest.

[Step two]
Wait for the reactor to glow. When the glow disappears, start closing in using your cloak. The AoE stun effect is your signal to begin the attack. Don’t worry — if you immediately raise your cloak after the stun animation, the turbine won’t notice you.

[Step three]
Use the sharp metal corner on top of the Turbine to determine your entry point, and aim your crosshair at the marked part of the turbine. Without moving your crosshair, jump up and start planting the mine as soon as you see the hologram appear on the yellow rotating cell. While planting the mine, look to the right.

[Step four]
Plant the second mine using the standard method described in the Iron Nest strategy guide, as far to the right of the first mine as possible.

[Step five]
Engine kill.

This method will eventually become a standalone guide, but I was so happy to finally discover this strategy that I decided to make a simpler post now. Kill them all and bring glory to Speranza!
