Had an idea for an AI plot, but wanted to get feedback here before I stick it on Mantis
After Hearteaterrightfully points out that the current AI beachheads aren't really beachheads (at http://www.arcengames.com/forums/index.php/topic,9906.msg93542.html#msg93542
), I got to thinking.
What about an AI plot where sometimes the AI tried to make an actual beachhead? Sometimes, send in some transports (not carriers, transports) and a couple of escort ships (some inside and some outside the transports), move to some "safe-ish" area of the planet. (Of course, the escorting ships would follow the transport, not just go out and attack)
Once there, it unloads the transports. Out pops not only the escorting ships inside the transports, but also a mobile builder or two, and some engineers, and maybe even a mobile repair station.
The mobile builders immediately start building some AI forcefields (numbers and marks of which depending on AI type, AIP, and current Mk. cap for waves), and an AI fortress (similar Mk. and count desicion process). The engineers of course assisting (prioritizing the FFs first, then the fortress(es))
Maybe even a cloaker starship or a scout starship in the transport for counter sniper protection.
As long as the mobile builders are around, the AI will replace lost stuff.
It turns out that the AI can build things just fine, even though they almost never do it now. You used to see it frequently back when the AI used turrets. Sure, they aren't held back by resources or energy, but they can still build. When building, the AI is subject to the same build time rules humans are. (And the same supply rules too, so this would be an adjacent to an AI world only tactic)
What would it accomplish, IDK. It would be annoying to the human to take it out, though, and would make future waves on that planet while the beachhead is still around much more deadly.
Triggering conditions are also TBD. Should it be a percentage of attack waves? Spawned off planet and then moved in (using similar rallying and escorting logic as exo-waves)? Don't know. It should definitely be an AI plot though. The existing beachheads plot should be renamed to something more appropriate.
