Operation: Angel | Walkthrough The Bureau Guide

Picnic quickly changes into the battlefield.

When you begin the mission, approach the police car and read a letter. Then enter the park in front of you. After a short walk you get to the place where three Outsiders and one Tech Commander are holding two moonwalkers. Lift the leader of aliens and fire him down, eliminating remaining enemies. At this moment, more Outsiders and four Drones (one of them Advanced) will join the battle. Take care about the flying ones, focusing them one by one. If you run out of bullets, don't worry: you find supplies on both sides of the cutting. In the house on left you find a letter explaining the current situation.

You can use alien weapon against aliens.

When you move forward, you'll be attacked by few more Outsiders. They aren't a challenge at this stage of the game: you have to watch out more to not step at the mine (there are two on your way). What's interesting, you can use this explosives against aliens - it's enough to fire at the mine when aliens are close to it.

Entrance looks impressing.

When you finish off aliens and collect bullets (shed can be found on right) approach moonwalkers and launch a mechanism next to them. When you finish talking with doctor Dresner move on, picking up a letter from corpses at right. When you get to alien structures, approach the device in the middle of platform and pick up Health Converter Pack, which decreases HP and abilities cooldown. Then, enter the building and from the armory on right take whatever weapon suits you. After that, enter the platform at which aliens are moving.

Muton dies within seconds under the heavy fire.

You find three Outsiders, with Tech Commander and an Elite Sniper on your way. First of all, eliminate the leader by lifting and killing him before he set up a Turret. Then, get rid of a Sniper and finish off the remaining aliens. When the last one dies, an Elite Muton appears. As he is alone, you shouldn't have problems with killing him (you can Lift him or lure down with Diversion and eliminate). Collect ammo from boxes on both sides of the battlefield. After that, enter the platform in front of you and release more moonwalkers. Behind a cover on right you should see two Elite Snipers and an Elite Outsider - take care of them without leaning out your head too often.

This machine was a boss once - not it's a piece of cake.

Move forward and fight three Outsiders and an Elite Sniper. When they're down, a Gunship with reinforcements emerges. Eliminate another squad of enemies and then fire down the alien vehicle. You have to be quick or the incoming Drones (two, to be precise) will quickly repair the machine. If you didn't make it in time, firstly eliminate the healing bastards and then the big plane. If you run out of bullets, look for in side corridors, there is a lot of different weapons and few ammo boxes.

When the battle is finished, approach the computer on the other side of the room and launch it. The mission ends.
