Mobile defense mission vs Spy missions

[OmgItsHongxD]

Was doing a solo syndicate mobile defense mission. Last one with 45 seconds left on it, went off to hunt medallions. The last console died, mission failed. This is the first time I've ever failed a MD mission and so it surprised me that failing one defense object would fail the whole mission. Unlike spy missions, where you can sometimes fail two and still win. Why is this?

Because its like sending a package of info between 3 stages. The result is only done by completing them all, like how you get a cryopod in that one mobile defense by doing the other terminals. Spy is hacking vaults, the vaults themselves aren't connected, they all hold something different.

It's simply a condition of these mobile defense missions, all three (or in some cases two) points have to be defended.

Mind you, some spy missions also need two or three successful data extractions, otherwise they fail. Sortie spy missions for example, always require three.

Generally speaking, it's a good idea to try and separate the medallion collecting with the objective of the mission. In captures, get your target a.s.a.p. and then try to find the marks. In rescue, leave the actual rescue for the end. In spy you can search at your leisure between data points. Mobile defense is a mixed bag, but it's better to get medallions while holding that oversized usb drive in your hand or after defending all points - at least if you play solo.
