Act 3 – Priority: Cerberus Headquarters

The Illusive Man’s headquarters have been located, and the Alliance is prepared to attack to recover the Prothean VI that holds the key to the Catalyst. Once the attack is launched, the Alliance will be fully committed to the final fight against the Reapers. Assault the base when ready.

MISSION BRIEFING

Battlegrounds: The battlegrounds in this mission vary from wide-open areas with multiple lanes of attack to tightly cramped walkways forcing you to engage in head-on battle.

Players who feel comfortable with diversity in action will do very well during this mission.

The battle picks up quickly as you face multiple Atlas Mechs, Centurions, and Assault Troopers. Luckily, the hangar bay’s a wide-open arena with plenty of cover lining the sides. Use flanking maneuvers or create a cross fire to catch enemies.

Vanguard players can use the wide-open area to rush to and fro as they demolish enemies using Biotic Charge.

Despite the seemingly labyrinthine corridors of the base’s sublevels, you’ll have plenty of room to maneuver and engage enemies from mid to close range. Turrets and force fields may make things difficult, but clever players with a wide array of destructive power combos will survive with ease.

About mid-mission, you will encounter a unique battle where you’ll be forced to engage Phantoms, Assault Troopers, and Nemesis fighters in tightly cramped catwalks. With no choice but to move forward, aggressive players will cut a swath across the walkways, stopping only to look back in the event that you’re being flanked.

Consequence Overview: Pre-mission, there aren’t many options to gain Paragon/Renegade points. As the mission concludes, however, you’ll speak with the Illusive Man and have the option to gain a few Paragon/Renegade points as well as use a Paragon/Renegade persuasion. If you’ve managed to persuade the Illusive Man across all other conversation, do so now to maintain your momentum.

Paragon/Renegade

At the end of the mission, you’ll also speak with the Prothean VI one last time. During this conversation, you’ll get a chance to use a Paragon/Renegade interrupt. The Renegade interrupt will happen first, so don’t use it if you want to use the Paragon interrupt.

SPEAK WITH DR. CHAKWAS

The end may be near, but that doesn’t mean the mood can’t be celebratory. Stop by the medical bay and speak with Dr. Chakwas (if she’s on your crew). She’ll suggest having a bottle of wine before the next mission. If you choose to do so, you can earn some Reputation points.

SPEAK WITH TALI

Tali isn’t feeling too hot after the events on Sanctuary. Visit her on the port observation deck as she sits alone at the lounge. Speak with her.

Upgrade Weapons and Reassign Powers

This is it, your last chance to purchase weapon and mod upgrades, or reassign powers. If you have any powers with points in them that you don’t use, spend a few credits to reassign all of your points and maximize their value.
