Mission Idea.
Operation: Nova Interception
Shepard get some intel that small pirate fleet of (few frigates and one light cruiser) will soon attack our colony. Best form of defense will be direct attack on them in space. But attacking with Normandy alone is to risky. Fortunately Blue suns contact with Shepard and offer their help ( Blue suns have few frigates).
Nows here what we can experience depending on decisions made in ME2:
a)Pirate Fleet is commanded by Vido
OR
Pirates are leaded by one of the power hungry commander that whant to gaind some resources in order to take over Blue Suns since Vido died.
b)Blue Suns that Contact with Shepard are splinter group leaded Zaeed.
OR
Blue Suns that contacted Shepard are leaded by other high ranking Member that want to take over Blue Suns
Now we can accept offer of Bule suns or not.
If we accept their offer we will be supported in space battle that will destroy all enemy frigates and end with boarding action on light cruiser with enemy commander on it.
If we refuse offer Normandy alone will mange to board light cruiser but couple enemy frigates will attack colony in the mean time. Witch in the end of mission will consequence with lost of many colonist and damage to most crucial buildings.
Second half of the mission is fight with blue suns on the deck of cruiser. Depending on our earlier decision we will be fighting alone with our team alone or be supported by blue suns.
After some shooting we finally manage to capture enemy commander. Here we can make another decisions.
a) Let him go ( The less profitable decision but some players might complain that it wasn't there)

Take him to intergeneration ( Our ally BS Commander will be most happy from this option while Zaeed will have a Mixed feelings)
c) Kill him ( Ally BS Commander will be neutral about that while if BS were leaded by Zeeed he will kill him personally)
d) Ally with him. ( This will lead to another fight against splinter group of Blue Suns. In the end Enemy commander will become our ally.)
