Edit: I tested it out in PvP scenario and its a bug, I've already reported it, perhaps ignore this until factorio team fix it.

In mission 2 it is possible to drive the black tank near the gate using remote drive, it have 200 AP ammo and solid fuel ready too, biters had no chance >:D
I have a feeling this is an engine issue that need to be reported to factorio form, I do not play PvP someone else could confirm it.

possible solution, remove the ammo/fuel from the Tank, so even if we remote drive it, It doesn't move/shoot, or remove the tank all together so it doesn't tease us 😂.

(thank you for maintaining this mode for 2.0 <3, greatly appreciated)

Hi, thank you for report.

This is very interesting because the tank in space port is actually different faction so I don't know, how this is possible. I must investigate this further. ;)

Hi again, I didn't find out the possible way to control the tank since it is different faction and not yours. How did you proceed exactly ? ;)

Hi, in factorio [2.0.20] if you are in remote view (default: tab), hover your mouse over enemy Tank or Spidertron then press the key to enter a vehicle (default: Enter), the tank need to be in radar/player view.

this bug is in the process of being fixed though ( https://forums.factorio.com/122610 )
I suggest ignoring it for now, sorry for any inconvenient.
