Litigious Rodent :
The choice here leads to no lasting consequences in any case.
- Deliver to TER. You lose the Moreya, and receive a Katana in exchange with the Yaki IFF. There will be a scripted fight in Savage Spur I.
- Deliver to Boso Ta. You keep the Moreya, and there is no scripted fight in Savage Spur I.
Both choices result in the free Syn. This step is completed independently of the next two.
- Tell Delilah that the Yaki are a threat. This results in a concentrated Terran attack towards Savage Spur I and the Yaki base by a very strong fleet led by an Asgard. You will receive guidance every 15 minutes towards the flagship until either it or the Yaki are destroyed. Presumably will remove the ability to start 'A Heart for Pirates' if this succeeds. Unsure if this will be averted by destroying the flagship.
- Tell Delilah that the Yaki are disorganized (Requires Dal Busta). No Terran attack occurs.
Mutually Assured Destruction :
- Place the navigation beacons leading towards Earth. Completing this step will result in Shinamon racing (very quickly) towards Terran Secret Service to inform them of your treachery. Failing to intercept him results in TER becoming hostile to the player. Successfully intercepting him results in no loss of rep. Completing the story from this point will result in a large gain in YAK rep, lockboxes with rare seminars, paint jobs, and upgrade components, and the ability to trigger a XEN invasion of TER space.
It is worth noting that this option does allow for the mission 'A Heart for Pirates' to occur, but only AFTER you pull the Xenon trigger.
- Destroy the signal amplifier. This can be done in the Katana, Moreya, or any other ship you manage to get over there, though it is somewhat difficult as YAK ships will attempt to stop you. You do have your allies helping with Shinamon and his little gang, however. Succeeding here results in Shinamon, a 5-Star Pilot, and his modified Kuraokami joining you. You will also receive a YAK rep gain, minus any loss from the amplifier fight, and several lockboxes with seminars and upgrade components. Also paint.
This line also results in 'A Heart for Pirates' without the need to unleash deadly machines towards TER Space.
- Tell Delilah the Yaki are a threat + Destroy the Amplifier. This may make destroying the amplifier easier as TER fleets tear through Xenon space. However, this usually results in the destruction of the Yaki, preventing 'A Heart for Pirates'.
- Tell Delilah the Yaki aren't a threat + Destroy the Amplifier. This will result in no attack on the Yaki, leaving destroying the amplifier up to you, but leaves the Yaki relatively safe from TER invasions, allowing 'A Heart for Pirates' to proceed unhindered, though you'll be on your own. Seems to be an intended 'Status Quo' option.
- Tell Delilah the Yaki are a threat + Mutually Assured Destruction. The Terrans will send their expeditionary fleet, and you can simultaneously pull the trigger sending Xenon towards Earth. This could be helpful if you intend to take Savage Spur for yourself- the Xenon guarding it will be gone, and the Terrans will be distracted from capturing the sectors themselves. Again, this will likely result in the destruction of the Yaki regardless, as the Xenon warpath does not intersect with the expeditionary fleet.
- Tell Delilah the Yaki aren't a threat + Mutually Assured Destruction. The Terrans will not attack Yaki space, and you will have a mission to pull the trigger sending the Xenon to Earth. Helpful if you want to weaken the Terrans without harming the Yaki. Can be especially helpful if combined with the TER/ARG plotline to weaken the Terrans even further. Once you pull the trigger, 'A Heart for Pirates' will begin, likely made somewhat easier by the Xenon evacuation of the sector.
This plotline involves you destroying the Xenon in Yaki space. If you manage to complete this, the Yaki become neutral with ARG/ANT/TEL/MIN/FRF/ZYA, and they will trade with them instead of raiding them. They remain enemies with TER.
