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?

this will not work on human players they can see the buildings constucting themselfs then they put a waypoint there and theyve got you :( but! it would work on the al players fine
