Hilarious strategy I thought up, The stealth generator rush Options

[Scary Monster]

This works like magic against the CPU and perhaps even against humans too if they neglect to make a mobile sensor array early.

Everyone knows the Subterranean APC engineer rush as Nod. It's a good idea to have an obelisk ready to plant the moment you capture a building.
However, if you have the tech to make a subAPC or obilisk, you also have the tech to make stealth generators. Have one of those ready and place it instead of an obelisk and the building you capture will vanish. If you still have engineers left over, you can freely capture and sell his radar (or war factory) so he can't counter with an MSA.
So long as the building you took stands, you can place a Hand of Nod next to it and pump out engineers. Every building you capture will vanish under the cloak.

If he has lots of defence structures you can freely build lasers or whatever in his base under the cloak. If they get too damaged, deactivate them so they recloak while you repair them as you build more. Just make certain you capture and sell either his radar or war factory to prevent him making a MSR.

If he's smart, he's already walled off his contruction site, but you should be able to cripple him anyway and have time to make rocket soldiers to punch a hole in that wall.
What do you think?

You're forgetting that human players can see the buildup anim of the Stealth Generator when you build it and they can place a waypoint on it, so they know where it is.
I really doubt this strategy 'd work against experienced players; they can simply send a bunch of units at you and you're finished.
This 'd only work as a good diversion...

Even though I usually don't play as Nod, this is how I'd do it...
Send subteranean SPC's filled with engineers and a couple others filled with cyborgs and rocket soldiers as backup at 2 different (as far away from eachother as possible) locations in your opponent's base, so you can capture structures at 2 locations. Build a stealth generator right away at one of those locations and build a hand of Nod at both locations right after that (so one Hand of Nod 'll be stealthed). If you have the time, build another stealth generator for the other Hand of Nod, but if you don't, just keep building defensive structures.
While you're doing this, it's possible your opponent doesn't have enough units to attack both locations where you captured a building in their base, or it distracts them to one location and don't get to see where you build the stealth generator. In the meantime you can also send a bunch of ground units at ther base (tick tanks, artilleries, etc.) and thus you're attacking your opponent from 3 different locations, the first 2 attacks drawing away the attention from the ground units you send in.

And now improvise...
