Manged to get a couple of missions played of Imperial Assault, I'll give an update on the first one for now.
After the Rebels scored a victory in the opening mission 'Aftermath' they felt pretty confident and embarked on a side mission called 'Friends of Old'. This was brought about after Gideon Argus, a founding member of Sabre Team was contacted by his old commander asking for help. Gideon had left Sabre Squad after a botched operation which was suspected to be sabotaged by a traitor in the ranks.
The suspicion of a traitor was proven when the rebels are attacked by Imperial fighters as they approach the planet, but their skilled pilot evades them and manages to land near to the rendezvous point.
The rebels start their search for Gideon's former comrades.
Initially, the rebels encountered light forces, an Imperial Officer with 3 Stormtroopers providing an easy encounter. But after some success, the Rebels got to the first possible location of a Rebel Trooper, unfortunately it was the traitor, revealed to be a high-ranking Imperial Officer who immediately attacked. One of the Rebel team was wounded in the fight and suffered a loss of some skills. More reinforcements arrived in the shape of a couple of Probe Droids and a squad of 3 Stormtroopers. The newly arrived Stromtroopers were very accurate in their shooting as they wounded another Rebel.
The Rebels then raced towards another possible captive and found one. They managed to give him covering fire as he made it back to the Rebel ship to score a success. The Rebels needed to find at least one more captive to complete the mission so they pushed on.
The Imperials had reinforced with an elite Stromtrooper squad and Probe Droid, these had gathered near to a prisoner site. The Rebel elected to go for the other site as the mission was becoming a desperate race against time. They did make it to the site but suffered another wounded hero, one more wounded hero would leave them unable to continue the mission.
The Imperials then went after the Rebels and wounded an already wounded hero, causing him to leave for the ship, unable to continue the fight. The rebels then tried to help the Rebel Trooper back to the ship, but the Imperials tracked him down and killed him.
Now with one Rebel Trooper left to rescue, it was going to be tough to free him with three heroes left, two already wounded. They pushed on but after an exchange of fire, another hero took a second wound and had to leave the battlefield. Desperately, one Rebel Hero ran towards the Rebel Prisoner and freed him, but took a wound in the process. This was his first so he could return fire on his attackers, killing a couple of Stormtroopers.
The other Rebel was surrounded by Stormtroopers and mercilessly gunned down, barely managing to escape back to the ship to lick their wounds.
The situation was now hopeless for the Rebels, the remaining Hero tried to give covering fire to the escaping rebel prisoner, but the Prisoner was cut down under a hail of Imperial laser bolts. Victory for the Empire!
