I have to say, the Saturn mission has some serious timing issues, so I'm glad to hear it's being addressed.
For some reason, Jacknife occasionally jumps in early before you even engage the last of the enemy wings - so the group jumps in and you have to take out Deimos beams while there are still 20+ enemy fighters in the sky. Good ****ing luck.
If that doesn't happen, and you actually manage to take out the Deimos beams, an adventure in and of itself because they keep turning, then the Indus gives the Carthage a chance to surrender, and it promptly blasts one of the frigates (Alta, usually) to pieces either with a beam cannon or flak. No matter, I think, perhaps this is scripted... but no, the mission ends and informs me I could have saved the Alta. Right.
I tried this on Medium, where I usually play (and have played the entire campaign to this point) and finally merged down to Easy after 8 failed attempts... and it's still not helping.
It might be doable if the Beam Dsiarming objective didn't fire until most of the fighter wings were eliminated, but as it stands I'm more often than not ending up with the enemy wings virtually intact and then getting an order to wipe out 8 beam turrets while the two Deimos corvettes spin on their axes making Archer use incredibly difficult.
I'm not sure if there's some unintended consequence of checkpoint loading happening here, but the timing in this mission can get seriously FUBAR'ed in a hurry. As it currently stands, 70 seconds is nowhere near enough time to disarm the beam cannons if so much as a single enemy wing is left.
