I really approve this Idea of a Virmire Survivor DLC, because I liked Ashley and Kaidan in ME1, but I felt really disappointed with their roles in Mass Effect 2. I just hope they get some more attention like Liara is getting, because I feel they are worth enough to get some "exclusive content". I agree 100% with this DLC idea.
To contribute to this "wishlist", I decided to point some things/ideas that I think would be acceptable/interesting in this DLC and maybe/even on ME3.:
*I don't really care if they both are on the same mission, with the same enemies and the same checkpoints (One mission for both would be easier for Bioware). As long as they get different dialogues, to show more of their personalities, I think that would be fine, but if Bioware make different missions for them, they are welcome,
very welcome.
*I don't really want to just receive a message and, on the first mission, see Ashley/Kaidan fighting and just join them for the rest of the DLC. I think there could be a "introduction" without them (To give a "history" touch), a mission to led Shepard to some other place that would the location to their "accidental" meeting. (Example: Ashley/Kaidan were sent by the Alliance to the planet "2" to investigate something, while Shepard would be assisting a facility under attack on the planet "1" so, on the end of the mission, Shepard would receive an information regarding that there might be more answers for that attack on planet "1" in planet "2" and then...you figure.)
*The meeting being marked by Ashley/Kaidan
saving Shepard's life and
not (once again) the opposite. Ashley should/could use her shotgun and some melee attacks against the enemy that is about to kill Shepard, just to finish him with another shot from her shotgun, while Kaidan
should use his biotics to destroy the enemy armor/body and then launch him at the enemies like a bullet.
*For those who want some non-combat moments, I thought, maybe we could do some "Gather X numbers of intel" kind of mission/achievement. I was thinking, maybe something like the "Noveria: Espionage" assignment we got on ME1, but for this, you would need to go to a (
new) place on the Citadel to find some "marked" people and hack some additional (but non-vital) information from them. For this, you would need to use Shepard or Ashley/Kaidan to distract the target while the other hack his/her information. For this kind of mission, Shepard and the VS would need to use clothes instead of armor to not draw attention, so, while you would do the mission with a new clothe (that, at the end of the DLC, would be selectable as a casual clothe for Shepard on the Normandy) you would also be able to see the VS using some casual stuff (and maybe showing us Ashley with her hair loose? I hope so

).
*For Hackett, I was thinking something like: At the end of the mission where you met the VS, he/she would see that his/her transport is in no-go, so he/she would have to go to the Normandy with Shepard. There, he/she would contact Hackett and tell what happened. Maybe the first dialogue between Shepard and Hacket could be like:
Hackett: Ashley/Kaidan, I am not receiving your Ship’s signal. Where are you?
Shepard: Don’t worry, Hackett, he is/she is in good hands.
Hackett: Sh-Shepard!?!?
Shepard: Hackett.
Hackett: B-But… I thought you were…
Shepard: Dead? Yeah…Let’s say it’s really good to be back.
(No, seriously, this was just an example. I really don’t know how would be their first dialogue in two years. I guess Bioware could create something
way better than this.)
And then some dialogue options would appear to know more about the Alliance, Hackett's Life in the past 2 years etc.
Depending if you betrayed Cerberus or not, he could say as his farewell, for example, that is “Really good to have someone that is willing to do the right thing not only for the exclusive good of the Alliance, but for the good of all the species in the galaxy” or “It’s good to know you’re alive. I just hope you realize as soon as possible what ‘those who try to show you that they have good intentions’ really want. The road to Hell is paved with good intentions. “
*For an "Normandy interaction", my idea was to make Shepard and the VS find some kind of encrypted data that would lead them to their final destination on the DLC, but for this you would need to let EDI do the decryption or the Alliance instead (If letting the Alliance do the decryption, then you would receive some "good points" with then, but if you let EDI do it instead, then let us say Shepard would be a little "unpopular" in the Alliance). While on the decryption process, Shepard could use this "free time" to show the new Normandy and it's crew to Ashley/Kaidan.
The Deck 3 (Crew’s Deck, in "the kitchen') would be a good place (Or maybe a new place on the Normandy?. It surely have the necessary space for another room, and a big one) to ask about how was the life of the VS in these two years, talking about the Alliance, his/her career …clarifying everything between the two of them. Also, this place could be used to show him/her that you quit with Cerberus or stayed with them, all of this would be available through paragon or renegade paths, but with the first one fixing things between them and the second one ruining everything.
(Note: I know that there will also be "Ashley/Kaidan haters" buying this DLC, so give those who “hate them” an opportunity to have fun, It’s their history after all and we can be rude with every, At least "nearly all", characters in the squad/game (The good renegade attitude). I think that, if they want, they should have the option to do this, as long as there are
no option(s) to kill Ashley/Kaidan (or anything else that could preclude them from ME3), I think it's fine.
To end that part of the DLC, I think the best way would be to bring him/her to the Captain's Cabin and talk about more important things. For those who not romanced, I think there could be another, more deep, talk about Shepard's loyalty to Alliance, wich could result in making him totally pro-Alliance or make the VS think twice about them.
For those who romanced one of them, the typical sentimental scene where we can see more of their personalities. Also, your initial dialogue could be better with then if you stayed loyal to them.( I hope they put some "kissing scene" or something like that if you stayed loyal, because if we need to wait until ME3...well, it will take some time).
For some reason, I think that "The Raven" (by Edgar Allan Poe) could be used in some part of Ashley's dialogue if you romanced her, but with some modifications like, instead of "Lenore!" (on the fifth paragraph) maybe "Shepard!"? Also, for some
another reason, I think Shepard could answer some of Ashley's questions with some poetry such as reciting "Love me" (by Walter Rinder), maybe? (Maybe using it
just before their romantic scene?)
*Also, I think that maybe the scenario on the final mission could remember Virmire itself, but much darker and frightening.
*I think that we should use the Hammerhead at some point, since using him would make seem that you are "sneaking behind the enemy's line". Using the Kodiak could be more pratical, but I don't think it makes you feel like "I am on a infiltration mission". Also, using the Hammerhead's speed to, let's say, escape from a place that is about to be destroyed would actually be very interesting, I think. (But, sincerelly, I would love to have the Mako for that kind of mission. I see the Mako as the perfect vehicle to make incursions, destroy enemies and bases or using it In missions like Vermire and Ilos, while I think that the Hammerhead is more like a tank to be used in rescues, hit and run tactics or things that don't involve him in heavy combats or really long missions, I don't know, but this is just what
I think.)
*The reason I wanted the final mission to be in a base like that used by Saren on ME1 is because:
The base would be heavy fortified, so a direct approach would not be advisable, being better to sneak through it. EDI could detect some interesting points that could be sabotaged, distracting the troops and damaging them and the base itself, like generators, fuel warehouses etc. But for this, you would need to choose a team to do this job while you, the VS and someone else would infiltrate the base (For this “choose a team” thing, you would
not lose
any of your squad mates in this mission, but depending who you choose, the process will be faster or slower. For example: 3 tech experts can do sabotages quickly while 3 soldiers can’t, but 3 tech experts, if detected by the enemy, will not be good enough in combat. They would have to fight longer while fight-specialized class characters could resolve this quickly. All of this while you fight some waves of enemies coming at you). To show the squad's progress, a Bar would appear and slowly be filled, showing the progress of them. Once the bar is full, the combat will be over or the sabotage will be completed (Combat’s bar could be red while the sabotage one could be blue to differentiate them). You would need to proceed until reach the determined location, through combat or, maybe, using your sabotage squad to distract your enemies so you could pass by them without getting noticed (I don't know how this last one could work, though).
Why a sabotage team? To make a "big epic final explosion" in the end of the mission. That's why.
Well, these are some of the ideas I had. I could put some extra things but much of them were already stated.
Also, I am making a "fan-made history" for this DLC or something that could be important for the history in Mass Effect 3. I am trying to use the "Dark Energy" topic as the "background history", so, maybe we could get some useful things in ME3, like making something that makes easier to biotics to use their abilities without exausting then in the process, making guns and shields of all kinds more powerful or even create our own "mass accelerator round", perhaps?. I think (At least I hope) it will be ready by the end of this week
Thanks for your patience.
