Read people's minds so we know how an infiltrator could enter the company.
Hack the internet for spying.
Ensure observers and Storm sensors can see into the Corp HQs.
Possibly recruit magical support, such as Ghosts or Gods or Spirits or Fate or something to act as guiding forces and spotters.
We're going to put together an infiltration team for each major area. It might be comprised of only drones, only spec ops units, only heroes, or some combination of the three.
The Infiltration team is to learn whatever it can about the four locations, possibly sabotage the Teleportation-blocker, electricity generator, base defenses, or such, then get the hell out.
They will have the full support of all the intel pertinent and updated as often as possible, and hopefully all of our legwork will be enough to let them finish their mission.
That's our plan for now.
After that, with our intel, we can sabotage the anti-teleport field directly (or just smash the fucking roofs in until we reach our target), drop in our attack teams, and bumrush our way to stealing Wily's Dataslate, Robotnik's bomb, the MetPharm time crystals, the Temple of Time's UFOPaedia, and get out.
At least, I think that's the plan. Is that the plan?
