Initial warpin is a single data can (red). Hacking it opens a gate that you take into the main room.
Some towers 250km away but don't attack.
I did Remote Defense Grid Unit first. It toggled a tower that is closer. Sniped it.
I did the 3 Coordinate Plotting Devices and got X, Y, Z objects. I placed them into Remote Calibration Device - Low Power. It said “Rift Calibrated!” and I should able to use the gate. I attempted to take the Calibrated Short Rift but nothing happened. Maybe I should have put stuff into the high power can.
Far away, other Remote Defense Grid cans.
