Introduction:
The year is 1962, CIA agent William Carter is recruited by the mysterious Bureau. Then aliens invade Earth and shit happens. Carter leads a team of two agents, tasked with repelling the invaders and investigating their nefarious plot. Gameplay wise the Bureau is a mix of third person shooter with some tactical elements, with some home base exploration thrown in for good measure. It should feel very familiar to players of the Mass Effect series.
Despite the XCOM series being infamous for its punishing difficulty, The Bureau is a walk in the park. The majority of the achievements will be unlocked through natural progression through the story, completing side quests and killing aliens with certain weapons or abilities. There are no achievements based on story choices or collectibles.
Abbreviated Walkthrough:
The Bureau has only a single difficulty related achievement, and it is for completing the game on the highest difficulty, Commander. People experienced with tactical FPS games, (EG Mass Effect and Spec Ops: The Line on the highest difficulty) should have no trouble starting on Commander difficulty, even on the highest difficulty The Bureau is very manageable.
My advice for playthroughs on Commander or lower difficulties is almost identical. I recommend completing all of the available side quests, the experience points earned from completing them will be helpful for the last few fights in the game. If you are starting on a lower difficulty, don't worry about getting 'No One Left Behind.' It is actually easier to do on Commander difficulty.
The first thing to remember is to make sure that none of your squad mates die. If one does die, immediately reload the checkpoint. Try to make sure to complete all of the side quests. There are three different types: Minor Operations, Dispatch Missions and Investigations. It is advised to complete all of the side quest achievements in one playthrough, as completing some of the Investigations are necessary to unlock enough Dispatch missions for the achievement. The Investigations are missable, but the game should give a warning if you are advancing past them. See the guide for lists of side quest progressions.
There is only one context sensitive achievement in the game, 'We Will Fight Like Lions!' This is acquired at the end of the first level, and is easy to miss being a secret achievement.
Mop Up:
The Bureau creates a new autosave at the start of every mission. (Similar to how the saves in Bioshock Infinite work.) This makes it possible to load up practically any point in the game and then continue on with the campaign to gain any missed achievements. 'Let the Boys Have Their Fun' is really the only achievement that won't be earned in normal gameplay, and it can be obtained quickly reloading an old save.
Hangar 6 R&D
Introduction: Hanger 6 R&D is the first and only DLC for The Bureau: XCOM Declassified. It is a prequel to the main campaign, where experiments DaSilva is participating in taking place in some hangers raises the ire of the aliens. In practice it's a series of fights in small environments, with a little down time between each fight. It is entirely separate from the main campaign, and there is zero carry over between them.
Walkthrough: The achievements are simple, easy and most will be earned through normal play. However a few are very easily missable. Things to remember are:
- Never use an alien gun or grenades (Microwave Gun and Lightening Cannon are OK.) See: Conscientious Objector
- Don't choose any of the Lift, Drone, or Mind Control perks when leveling up. See: Only a Man
- Get a Squaddie of every class to rank 5 and take them in a mission. See: Know Your Groceries
Otherwise you're fine to carry on and kill aliens.
Note that DaSilva plays somewhat differently than Carter, and benefits from a more offensive playstyle. This will be apparent if you choose the perks for the Only a Man achievement, which makes him into even more of a glass cannon. It pays here to be aggressive and use the bombs like grenades when the aliens spawn in. As DaSilva comparatively lacks defensively, be sure to use the squaddies and their powers as a distraction and to draw fire to keep yourself from being overwhelmed.
Mop Up - Note that many achievements from the main achievement list can be earned in this DLC campaign. (Kills, Difficulty and Squadmate related achievements.) This is a very good place to get any achievements from the main list you may have missed. This is especially useful for getting No Man Left Behind(No squad-mate deaths). On Impossible difficulty the DLC campaign is harder, but it is much shorter.
Conclusion:
This is a fairly quick and easy list. Almost all of the achievements can be done in a standard playthough, and it is quick and easy to reload saves to get any missed achievements.
