Fallout 4 Trophy Guide
Most people hit 1000 completion on their first run and still miss two or three trophies because they didn't plan ahead. I went through this on three separate playthroughs before getting everything without loading old saves, and the main issue always came down to build choices and missing NPC interactions. This guide breaks down every achievement, which ones are mutually exclusive, and where you will lose time if you are not careful. There are five or six trophies that people rush through and then realize too late cost them time. The first one is Weapons Free, which requires killing 100 enemies with a weapon. This is trivial if you use any rifle with high rate of fire, but it becomes annoying if you are playing with a .44 pistol or a bow as your main tool. Switch to a laser pistol or a sawed-off shotgun early and farm raider camps. The second is Locksmith, which needs 100 lockpicks. Do not overthink this. Open every junk bin in the game. By the time you complete side quests, you will already have more than enough. Just keep one pick in your inventory at all times and craft more when it drops below 20. The third common mistake is the Pacifist trophy, which sounds noble but is extremely restrictive. You cannot deal damage with weapons during the entire main questline. Melee weapons count as deals in the game code, so even a single swing that connects with an enemy during a cutscene will break the trophy. The only reliable workaround is to use non-lethal takedowns exclusively until you reach the final boss, then use the Power Armor to block rather than attack. This method works, but it slows your progress significantly.
Building characters that do not break trophies
Some achievements require specific skill levels. Mister Handy needs you to level up the Robotics Expert perk, and Shahvee requires raising your Barter skill. The problem is that these perks conflict with stealth-based builds. If you put all your points into Sneak and Perception early, you will struggle to reach perk level 3 in Robotics without spending multiple perk boxes later. The fix is simple: allocate one perk box per level to the skills you need for trophies. Do not invest heavily in any single skill tree until you finish the main story. Another issue I encountered involved Strong Friends, Long Lives. This trophy requires completing companion quests for four different followers. I learned the hard way that companions can become hostile if you fail their individual quests, which locks you out of the trophy permanently. The workaround is to save before every companion quest and reload if their dialogue turns negative. I spent about 40 minutes this way across two different playthroughs before I memorized which quest lines had branching outcomes.
The difficult collection trophies
Wasteland Wanderer demands visiting 50 unique locations. Most players miss 5 to 10 locations because some are hidden behind doors or require specific keys. I found that the easiest method is to complete the Railroad questline first, since it unlocks fast travel to hidden locations across the map. After that, use the Pip-Boy map filter to mark undiscovered locations. Do not drive everywhere. Walk to nearby unmarked spots and enter buildings to trigger location registration. This approach reduced my total time from about 8 hours to roughly 3 hours. The hardest collection trophy is Treasure Hunter, which requires finding 100 legendary items. These spawn randomly and have a very low chance per combat encounter. One practical method I used was to farm the same legendary room repeatedly. The Nuclear Winter DLC area near the Glowing Sea has a consistent spawn rate for legendary creatures. I ran that area with a heavy weapon build and collected 12 legendaries in a single session. Avoid farming legendary robots unless you have a high Perception build, because the spawn rate drops significantly compared to humanoid enemies.

The mutually exclusive path
The most damaging decision in the game is choosing between the Institute, Brotherhood of Steel, Minutemen, or Railroad. Each faction ending locks you out of companion quests and some side quests. Aid Station, which requires healing 500 wounded enemies, becomes impossible if you side with the Brotherhood, because their questline eliminates many factions that provide wounded targets. I recommend finishing the main story as a Minutemen player. This route leaves all other factions intact and gives you access to every trophy. If you choose the Institute, you will lose access to Underground King, which requires clearing the Glowing Sea. The Institute storyline prevents entry to that area until very late, and some players never reach it. The workaround is to complete all Glowing Sea exploration before accepting the Institute quest. I spent about 6 hours in that area alone because the radiation and mutant spawns slow movement significantly.
Trophy that requires manual difficulty manipulation
Tour Guide asks you to survive a certain number of damage-over-time effects without dying. I found that changing the difficulty to Hard and using the Combat Armor with the Radiation Resistance perk made this much easier. The key is to stack healing items and armor-piercing rounds. One specific edge case I encountered involved the Nuka World DLC. The DLC introduces a new type of toxic effect that does not register under the standard Survival mode unless you have completed the main quest. I solved this by replaying the Nuka World questline on Normal difficulty after finishing the main story. This added about 3 hours of work but did not break any other trophies. Completionist requires 100% completion of all in-game objectives. This means every quest, every ally, and every location. I completed this trophy on my third playthrough after realizing that some quests do not appear until the fourth quest stage. The most important detail is that Radiation is an objective in the main quest, and failing to complete the Radiation phase disables several side quests. I recommend using the Fallout 4 Trophy Guide as a reference point during each quest to verify whether the objective is truly complete. Many players assume a quest is done when it is actually pending a trigger event. Save often. Load old saves only when a trophy breaks due to an unavoidable narrative choice. The game does not auto-save during companion quests, so you must manually save before entering quest areas. I once lost a trophy because I forgot to save before a dialogue choice, and reloading from the last auto-save was impossible. That cost me about 2 hours.
The total time to complete all trophies on a fresh save is roughly 80 to 100 hours if you plan carefully. Rushing through without checking the guide can easily add another 20 hours due to missed objectives and bad faction choices. Use the map filter, keep perk boxes allocated evenly, and avoid locking yourself into faction-specific endings until you have finished the companion quests.
