Of course it works, that is just a lame excuse, if I ever heard one...
The only minor glitch I ever run into is that quite often you have to re-issue the HOLD POSITION
order, as after a short while, units tend to ignore it for some reason, and start moving around again.
Very rarely, the same thing happens with HOLD FIRE
or RETURN FIRE ONLY
orders, which is something I always use, especially when I attack the very last scavenger outpost, at the end of Campaign Alpha 1, so the mission will not end, since it is the only one with no mission timer, thus you can "milk" it for power build up.
I always leave the Scavenger Power Plant in that outpost intact, get the artifact, do the all 3 steps of the resulting research, and leave the game on for a few hours, until my power gets well above 25,000 or so (or if I don't have the time to wait, I just use the DEBUG mode, speed up the game to x100, and get all the power I want in like 2-3 minutes). Other than that, all works just fine.
Some will say that's cheating, I say it's a good strategy. What can be more frustrating than to need power for building units or defenses or for research and not having it??? Well, the use DEBUG mode part kinda is cheating, I admit...
Watch the video...
As you can clearly see by the video, once they have locked onto the units that are running away, they will go after them at all cost, and they don't care about other threat levels or anything else around them.
There are a few times the units go out of sight range as well, and the units still pursue them.
Now, can we agree that it is working, as it should in the video?
