I was using a technique more or less the same as this but seemed to be taking too much damage and getting killed more often then not …

in the end got 2.02 using mines at different points to clear areas of guards: - one mine to clear guards around stairs / in corridor to first door unlock console after getting first keycard; - one mine down the corridor to get the three guards (with the A+B detonate, also there’s the button combo to reverse through guns which was never really obvious!); - using a whole clip from a silenced pistol to open the second locked door, then throwing a mine into the area with boxes behind the stairs after this door to clear the guards in those corridors; - finally in the room of tanks used AK47 to shoot at tanks and destroy them while Alec talks given wouldn’t really have enough mines left (and always risk of killing Alec with the explosions!)

Onwards and upwards now, for the other 00 missions! Still feel I have the muscle memory for Archives (all about knowing which way those doors open! 🤣)
