How to unlock the Cyberlord achievement in XCOM 2 - Definitive Guide
*Mark II upgrades require researching the Advent MEC Breakdown; Mark III upgrades require researching the Sectopod Breakdown.
Assuming you're attempting to hack a mechanical unit, it's also possible to shoot it with Bluescreen rounds first as these will reduce the hack defence on a successful hit.
Alternatively, if you own the "Shen's Last Gift" DLC pack it's possible to get this done much easier, and certainly much earlier it could be completed in your campaign otherwise.
During the "Lost Tower" mission, Lily Shen will be part of your ground team and if you attempt it as soon as it's available in your campaign she will be significantly better than any other Specialist you have available (she's the equivalent of a Colonel with both perk trees unlocked). Simply use her for all hacking opportunities (the elevator console in the first segment is ideal), and she should be able to get the better reward with ease.
While on this mission it is also possible to get the following achievements the same relative ease:
Whenever you hack a target (such as a door or computer but not an enemy), you will be given the choice between two rewards. The second reward is generally better but has less of a chance of success. In order to obtain this trophy, you must be successful in obtaining the second tier reward. There is no penalty for failing to obtain the reward (the hack itself will still be successful) so you could simply hack objects and selecting the second reward until you get lucky. Alternatively, you can increase your chances by having a Specialist do the hacking (any classes are capable of hacking but Specialists are better at it). You can increase your odds further by equipping the Specialist with a Skulljack or higher tier GREMLIN. Both of these increase the hacking ability of the Specialist.
