Operation: Grifter | Walkthrough The Bureau Guide

There is a sniper on right.

When the mission begins, go forward and try to get as close to the enemy position as you can. On the farm you find several Sectoids, one Outsider and one Rocket Sniper (marked on the screen above with "X"). You should eliminate the sniper first, as he has the biggest fire power in this set (one shot from sniper rifle should be enough). Remaining enemies shouldn't be a problem, but this is - unfortunately - only a recon group. And you'll get to know that really quickly - when Carter eliminates all aliens, several more Outsiders and a Drone appear on the battlefield. Your priority is, of course, the flying thing, because it can heal allies. So get rid of him first and then eliminate the rest of dangers (mobility is a key, aliens have a lot of grenades!).

Enter of the Silacoid isn't subtle.

When you kill all enemies and collect ammo (from the cars) head for the shed. Inside, turn left and enter the small room where you kill Silacoid. Notice also, that there are two types of weapon on the floor: shotgun and Laser Pistol. You can pick them up if you want.

The difficult part begins further on.

Go through the shed (killing another Silacoid on your way) and exit through the door on the backs. Look to the Resupply Station on the shore and go to the river. Follow its current and you get to the locations shown on the screen above. Jump down and kill two approaching Silacoids. Then, use a footbridge which was abandoned by those monsters. This takes you to the further part of the location.

Look for Schematics.

Go forward until you get to the ruined wagon. Look inside and pick up Gunner Pack Schematic, which decreases amount of obtained damage and increases capacity of clips. Then kill another Silacoid, who will try to attack you from behind.

Drones appear rather surprisingly.

When you move on, you get in between trains. Here, you find three wandering Outsiders, which you can take down easily (they're not expecting an attack). When it's done, three Drones and few more Outsiders will get out from the wagon on right. Eliminate the first ones quickly with Critical Strike or with sea of bullets. Notice that Carter's squad mobility is very limited in here: there is a plenty of deadly mines around. If you have to avoid enemy grenades, shoot at the mine first and then try to tumble.

Killing Muton may take a while.

When you go through the wagon from which Drones and Outsiders emerged, you'll notice artifact sought by the Bureau. Unfortunately, it will be stolen by the alien which cannot be stopped (he is immortal). What's left, is a powerful Muton on the battlefield. Use grenades, mines (if you have an engineer), Diversion (recon) and bullets to eliminate this threat. Probably, you'll use a majority of your supplies in this fight, but you can replenish it thanks to packs in the nearby wagons.

Forcing enemy to move through train is a perfect tactic.

Notice, that enemy is supported by an Advanced Drone, who has nasty ability which lifts Carter's companions. Eliminate him first, otherwise the battle will last forever.

If this encounter is difficult, you can play game of a cat and mouse. Muton is so big, that he can't move between cartons on left. As he is forced to move every time through the wagon, he is an easy and not mobile target. Use it, setting up mines or throwing grenades.

Here comes your goal.

When the fight ends, go through the carrier in front of you and pick up artifact. In this moment the mission ends.
