If you’re the type of looter shooter fan who chases 100% completion every time you pick up a new game, you already know how annoying it is to hit 95% progress and realize you missed a random, time-sensitive achievement 20 hours earlier. Borderlands 4 is packed with chaotic fun, weird side quests, and endless loot, but its achievement list has a few tricky surprises even long-time franchise fans might miss. This guide breaks down everything you need to know about Borderlands 4 achievements, from missable mission-locked rewards to fast grind tricks for the most tedious unlocks, so you can get that full completion badge without replaying the campaign three times.
How Borderlands 4 Achievements Are Categorized to Simplify Your 100% Grind
Before you dive into hunting every unlock, it helps to understand how the game sorts its achievement list, so you don’t waste time chasing something that’s tied to content you haven’t unlocked yet. Unlike previous Borderlands games that mixed all achievement types into one unfiltered list, Borderlands 4 splits its base-game achievements into five clear categories, even if the hidden ones don’t show up until you unlock them. The list has a total of 65 base-game achievements, with 15 more planned for post-launch DLC, but this guide only covers base-game unlocks so you don’t get spoiled for unreleased content.
Most players will unlock around 30% of the total list just by playing through the campaign normally, without going out of their way for extra challenges. The side content and combat challenge categories are where most people get stuck, since some of them have very specific requirements that the game doesn’t explain clearly. The co-op and hidden categories are usually the last ones players finish, since they require either playing with others or hunting for unmarked secrets the game never mentions.
Missable Borderlands 4 Achievements You Need to Grab Before Beating the Final Mission
The worst feeling for any achievement hunter is finishing the final boss, hopping into free roam, and realizing you can no longer unlock an achievement tied to a specific story choice you made 15 hours earlier. Borderlands 4 only has 4 missable achievements, but they’re easy to skip if you’re rushing through the campaign without paying attention to side dialogue or optional choices. I missed the "Merciful Outlaw" achievement on my first playthrough because I shot the bandit leader Razor before he finished his monologue at the end of the "Good, Bad, and Outlawed" side mission, and I had to restart the entire campaign to fix it.
All 4 missable achievements are tied to choices in side missions located in the first three open world zones, so you don’t have to worry about missing anything once you reach the final Vault planet. None of these missable achievements are tied to main story choices, so you can pick whatever dialogue options you want for the core plot without risking your completion run. The other three missable unlocks include one for collecting all 12 alien skulls in the Dust Plains before you complete the "Alien Relic Hunt" main mission, one for sparing the robotic bartender in the Sanctuary side quest "Last Call", and one for beating the first world boss without using any legendary weapons.
It’s a good idea to keep a small checklist handy for these four achievements as you play through the first half of the game, so you don’t forget to grab them before you move to the final zone. If you do miss one, you can restart the campaign on easy mode and rush through the first 10 hours in about 2 hours if you skip cutscenes, but that’s still a huge waste of time you could spend grinding for better loot or playing co-op with friends.
Easy Tips to Grind for Difficult Borderlands 4 Achievements Without Wasting Hours
Some Borderlands 4 achievements sound incredibly tedious on paper, like killing 1000 enemies with elemental damage or reviving 50 teammates in co-op, but there are tons of shortcuts to cut your grind time in half. The best part is that none of these shortcuts count as exploits, so you don’t have to worry about getting locked out of achievements or banned from online play. I used most of these tricks to cut my total 100% playtime down from 80 hours to just 62, so I can confirm they work perfectly.
For combat-related grind achievements, the best farming spot is the respawning bandit camp in the northern part of the Dust Plains. The camp has 20 low-level bandits that respawn every 90 seconds, and there’s a fast travel point 30 seconds away from the camp entrance. Turning on Mayhem Mode 3 won’t invalidate any achievement requirements, so you can run this farm on higher difficulty to get better legendary loot while you work through your kill counts. This spot works for almost every combat grind achievement, from elemental kills to critical hit streaks to shotgun-specific kill requirements.
For co-op exclusive achievements, you don’t need three other friends who also want to grind achievements. Most public co-op lobbies are filled with players who are also hunting for unlocks, and you can even find dedicated lobbies specifically for achievement grinding by checking the lobby description. Most players are happy to help you get revive counts or 4-player mission completions, as long as you’re willing to help them with their unlocks too. You don’t have to be the host of the lobby to unlock co-op achievements, so you can join random lobbies and get credit for all completed requirements without having to organize a group yourself.
For the achievement that requires you to hit level 50 with all four starter characters, you can cut your grind time in half by using the game’s shared XP system. Every mission you complete gives XP to all characters in your roster, not just the one you’re currently playing, so you can swap characters every 10 levels to spread the XP evenly. You don’t have to play each character for 20 hours straight to get them to max level, and you can even run the same high-XP side mission over and over to level all four characters at the same time.
Hidden Secret Achievements You Won’t Find in the Default In-Game List
If you’ve completed every listed achievement and you’re still stuck at 94% completion, you’re missing the hidden secret achievements that don’t show up in your in-game list until you unlock them. There are 6 total hidden base-game achievements, all tied to Easter eggs and unmarked optional activities that the game never mentions in tutorials or quest prompts. None of these achievements are tied to paid DLC, so every base game player can unlock them without spending extra money.
The most popular hidden achievement is "Pandora Pizza Party", which requires you to collect 8 hidden pizza slices scattered across every open world zone. Each slice is hidden in a hard-to-reach spot, like on top of a cliff or behind a hidden wall in a bandit camp, and you get a hint for each slice’s location if you listen to the random radio broadcasts scattered across the map. Unlocking this achievement gives you an exclusive pizza-themed weapon skin that works on all legendary shotguns, which is one of the coolest cosmetic rewards in the entire game.
Another hidden achievement is "Vault Hunter Tribute", which requires you to interact with the statues of the original four Borderlands 1 vault hunters in the new Sanctuary hub in a specific order. The order is hidden in the graffiti on the walls near the statues, and you unlock a secret retro minigame that lets you play a 16-bit version of the first Borderlands vault fight once you get it right. You can unlock this achievement as soon as you get access to Sanctuary, which is about 3 hours into the campaign, so you don’t have to wait until the end of the game to hunt for it.
The last hidden achievement is "Lucky Claptrap", which requires you to find and press 10 hidden buttons on Claptrap’s body scattered across different areas of the game. Each button is hidden on a random Claptrap NPC in a side mission or hub area, and you have to interact with each one before you finish the associated side mission to get credit. This one is a little tedious, but it unlocks a custom Claptrap companion that follows you around in free roam, which is well worth the effort for long-time franchise fans.
Borderlands 4 achievements are designed to be a fun bonus for players who want to explore every part of the game, not a frustrating chore that forces you to play in a way you don’t enjoy. If you plan ahead for the 4 missable unlocks, use the grind shortcuts for the more tedious challenges, and hunt for the hidden Easter egg achievements, you can get 100% completion in around 60 hours, which is far less time than most other modern looter shooters require. The cosmetic rewards you get for unlocking all Borderlands 4 achievements are also a nice bonus, and you’ll get a special "Master Vault Hunter" title that shows up next to your name in every co-op lobby you join, so everyone can see you’ve explored every corner of Pandora’s newest chaotic adventure.
