Mega Man Zero 2/Residential Area

Once you've completed the list of missions Elpizo has requested, leave the command center and return to trigger a cutscene.

The Strike Begins
When Zero returns to the command center, a soldier will also arrive to report in to Elpizo. Elpizo has already sent a large amount of his troops to Neo Arcadia to prepare to begin "Operation Righteous Strike." The soldier says his men are ready to open fire, and his lieutenant Pasosu awaits his signal. Elpizo's eagerness to begin his attack is evidenced by his desire to destroy Neo Arcadia once and for all. He gives his thanks to Zero, and then gives the order to attack, but is halted by Ciel.

Ciel immediately rushes into the room, followed by Cerveau. Ciel tries to convince Elpizo he's making a mistake, because this attack is to be conducted on a weaker, residential district, and could very well mean extremely high casualties. Elpizo's simply accepts that possibility and dismisses her concerns. However, Cerveau tries to intervene as well and mentions Ciel's research is almost complete, and she'll have the solution to the energy crisis that would stop Neo Arcadia from doing anymore harm. Elpizo thinks Neo Arcadia can't be trusted, and refuses to stop his attack again.

When Ciel tries to plead with Elpizo again, he finally snaps and loses his gentle demeanor. In a fit of rage, he reveals how worried he is about everyone, and shows how much paranoia and frustration Neo Arcadia has really caused him.

Enraged beyond reason, Elpizo gives the order to engage and open fire. Everyone is too afraid from his outburst to question him again. Jaune, the operator on the right, relays the order to the troops, and they begin the attack. Elpizo requests transfer to the front lines to give commands, and he and the last soldier in the attack force are sent there as such, but not before Elpizo tries to justify his anger.

Ciel runs off in anguish, while Cerveau asks Zero to follow Elpizo, having a very bad feeling about the attack, along with Rouge and Jaune, the operators. You can chose to say no, but there's really no point. Say yes to be transferred to the Resdiential Area...

The Strike Fails
As soon as Zero arrives, it's a sight of pure carnage. Lifeless Reploid soldiers lie all over creation, and the aftermath of the destruction is everywhere. It looks like the operation was a complete failure, and it's time to rescue Elpizo before he meets his end...

Right as you head down the morbid hallways, you'll run into Gli-Eyes from the last game, enemies that swoop in to attack. Don't make much of them and wipe them out as you find them. Destroy 5 for Cyber-Elf Bircarry.

Along with the Gli-Eyes are Pantheon Guardians. Since the Residential Area is the place where they naturally appear, you can finally get a Cyber-Elf out of smashing them to bits. Destroy 8 for Cyber-Elf Beebite.

Cyber-Elf Sub Tank #1
Further along the hallway are two cleverly-positioned blocks, one covering up a Cyber-Elf Box. Pass by the one on the ground and drag it over to the right as far as possible with the Chain Rod to give yourself enough reach to pull the other one out on top of it from the ceiling, which you can do by yanking on it diagonally from the upper right. With the passage opened up, you can claim Cyber-Elf Estan. This is one of two Cyber-Elves that will transform into a  Sub Tank upon use. However, unlike the Hidden Sub Tanks, you'll suffer a penalty for using these, just like in the last game.
