While I agree that getting this voice-acted would be marvelous, let's at least get the first two acts (E1 and E2 missions) finalized before putting them out there.
I'll test out E2M1 later today and make sure everything is working. The debriefing I've already written. I'll see how the mission plays out with the current events, and script 3 or 4 transmissions accordingly.
The way I conceptualized it in the debriefings (and the way I'm planning to write the lines, unless told otherwise) is that the Nicholas is a bonus objective - you don't HAVE to protect it, but if you do you get rewarded for it.
This is just preliminary (without playing it since the changes) but here are my suggestions - don't add this text, I'll re-write it, but it'll be something like this (additions, this is keeping all existing lines). You may need to add an event or two - I'm assuming here that in order to complete the mission all transports must survive:
Event: Nicholas is fired upon by the Moloch and severely damaged.
Message: Nicholas-"Command, our hull integrity has been compromised by the Remhas! We are recharging our jump drives now, but we need additional cover!"
Command-"Understood, Nicholas. The Tatenen is preparing to launch fighters. They will be on station within a few minutes. Alpha leader, your mission is to protect the convoy. Protect the Nicholas only if you can still accomplish your primary objectives."
Event: Shivan fighters jump in and target the Nicholas.
Messages: Nicholas-"We have been targeted by <wing name> wing! Our jump drives are still recharging! We won't make it without fighter cover!"
Tatenen-"Our fighters are not yet ready for launch, Nicholas."
Event: First transport jumps out, Nicholas is still in system (along these lines, make sure the Nicholas doesn't jump out until AFTER all transports leave the system).
Messages: Medical Ship-"Thank you for the cover, Alpha and Beta. We'll be jumping out shortly. Help that cruiser!"
**Note: the transports should still be vulnerable for several seconds here, so if the play DOES abandon them at this point there should be some chance of one getting taken out and the mission failing.
Command-"Alpha and beta, engage all remaining enemy craft. All convoy ships must make it through the portal. The Nicholas is not your responsibility."
Event: All enemy craft destroyed, Nicholas survives, bonus objective complete.
Messages: Wingman-"Nicholas, you still with us? Looks like the area is secure."
Nicholas-"Our jump drives have recharged. We're getting the hell out of here. Thanks for the assistance, Lonestars!"
Event: Nicholas is destroyed before the convoy jumps
Message: Wingman-"Alpha leader, the Shivans just destroyed the Nicholas!"
Command-"Lonestars, focus on your mission. Protect that convoy!"
