Honor, Pride, and Regret is the squad story focused on Rebecca, Mabel, and Fleuret. The combat mission in this is Brave Hearts.
This map takes place in the same one as in phase two of Chapter 01: The Battle of Fort Krest. Minor differences include grenadier shelters on the bridge and outer battlements, and indestructible walls and barricades scattered throughout.
Squad E and their base camp start at the north point of the map, while their main objective lies on the other side of the bridge. In addition, there are two other Imperial camps that are on the upper levels of the castle.
Allow me to brief you on your mission
"Squad E's task is to drive off the Imperial forces attacking a Federation fortress. According to recon, the enemy troops are few in number - but that's no excuse to slack off."
Location: Refortified Castle
Description: Challenge the advancing Imperials to a duel by capturing the enemy base camp. The mission will end in failure if Fleuret, Rebecca, or Mabel meet an untimely demise.
