How to unlock the False Sense of Security achievement in Stormrise - Definitive Guide
I tried it on PC and is a solution coming originally by Ianuvan
On mission 3 (the first one you get a vehicle in)
From the start portal go up and capture the node to the right, it doesnt have any turrets so just send up 1 group of infiltrators. Once you capture this you will get given 2 sets of enforcers. Kill the enemies that rush you and then send your infiltrator down the gap on the right side.
"However it's easier to find it by skipping the part about getting the first node.
Where you first spawn there's a path to the right around that node. You'll still get attacked so I brought my comm unit to take care of those guys. Then continue towards the corner and save just where you said."
Save before turning the corner at the end and then go round. You should see another enemy node and the outline of the spectre to the left of it. The node has no turrets so just press Alt, stick on your thermal vision and then shoot him. Once he is dead, exit to menu and then press continue, should bring you right back in before turning the corner. Rinse and repeat 23 more times.
There is also a second cloaked Spectre just after the next green objective control point (where you need to go "underground" to get there) - the Spectre is just beyond the control point and around the corner to the left (out of sight from the control point) on the same platform. Pick one and do the reload trick. Easy.
There is a very nice spot in the campaign to grind this. In Mission 3, when your start the level, you have to capture two nodes and occupy a collapsed building which serves as a bridge. Once you're done with this task, send infiltrators to the right hand side node. Once there, continue further to the northern path until you go under the collapsed building. Don't actually go under it, stay there and if you look away before you, you should see a node, with a cloaked spectre next to it. Save your game, activate thermal vision and the spectre should be dead in no time. Now leave without saving then choose to continue from your last checkpoint. Rinse and repeat 23 times and you'll unlock the trophy.
Mission 3 is the best place for this (although again, it can be done in MP, just faster in campaign). Right at the beginning, capture the primary node as instructed, then if you look toward the main battlefield capture the node in front of you and to the right. Kill the units that attack you and then send infiltrators through the rubble along the right and under the building. There is a node that you need to capture anyway, and right next to that node is a cloaked spectre. Save before you turn the corner, have your thermal vision on, headshot, load, repeat. Very fast.
