Mhh.. in mission 8 "Ambushers from the shadow" there are two achivements.
Actually i am asking if it is possible to get the first one and also the keep the Meleager beams intact?
I am only able to get it, if i am waiting for the Infiltrators at their entry point and blast them out before their missiles knock out the main beams.
Actually i was never able to keep the Meleager beams intact, because the Infiltrator are starting their fire even before their warp effect disappeared.
Should the player not have a few additional seconds to destroy them before they start to fire?
So there is a strategy to get the Achivement, but not to keep the beams intact in the same time. So that feels more like a exploit for me.
Ah btw... what i kind of dislike in this campaign is, that there seems to be a mission specific arrival message for most of the enemies in the missions... but that is always played simultaneously with the general voiced arrival messages from FS2... that is very weird, because it is also a matter of luck which of the two arrival messages is shown in the center of the HUD...
