Borderlands 2’s base game ships with 50 achievements worth 1,000 Gamerscore on Xbox and 51 trophies including the Platinum on PlayStation, and a focused solo run to 100% takes roughly 60–80 hours on a single character. Only a small group of them are genuinely missable — the ones tied to rare enemy spawns, a randomly placed Sanctuary NPC, and named locations that exist only inside one-time story areas — so the safest plan is one completion character who does every side mission and clears every map as they go. Everything else, including the long grind behind “Challenge Accepted,” can be mopped up afterward in True Vault Hunter Mode.

The base game list at a glance

The 50 base achievements break into six groups with very different time costs. The counts below are the base-game list as tracked in the in-game challenge and mission menus; the DLC lists sit on top of these and are counted separately.

Group	What it covers	Count	Realistic time	Missable risk
Story and boss milestones	Main mission completions, opening the Vault, defeating Handsome Jack	12	20–25 h	None
Side missions, NPCs and vendors	All side quests, Michael Mamaril’s gun, tipping Moxxi, Eridium Black Market purchases	9	8–12 h	Low to moderate
Exploration	Discovering every named location in each region, plus the global “World Traveler”	5	4–6 h	High
Class skill kills	One per playable class — Sabre turret, Phaselock, Gunzerk, Decepti0n, Deathtrap	5	2–4 h each	None
Combat oddities	Goliath leveling, Donkey Mong, rare Chubby spawns, thrown Tediore kills, Constructor kills, Badass tokens, customization unlocks	18	6–10 h	Moderate
The grind	“Challenge Accepted” — complete level 1 of every non-level-specific challenge on one character	1	15–25 h	None, but it is the long pole

Achievements that can actually slip past you

Most of the list is unmissable because it is tied to the main story. The ones below are the exception, and they are the reason a completion run should be planned rather than improvised.

Achievement / trophy	Trigger	Where	Why it gets missed
Tribute To A Vault Hunter	Pick up the weapon dropped by Michael Mamaril	Sanctuary — four possible spawn spots	His appearance is random, so players finish the game without ever seeing him
Definitely An Italian Plumber	Kill Donkey Mong	Eridium Blight	Rare spawn; players clear the region once and move on
Cute Loot	Kill a rare oversized enemy variant (Chubby / Loot Midget)	Any bandit-heavy map with chests	Pure chance; it cannot be forced by clearing a map
Exploration set (Arctic / Urban / Highlands / Blight Explorer and World Traveler)	Discover every named location in each region	All regions	Several locations exist only inside one-time story sequences, so the fog has to be cleared before the mission ends
Did It All	Complete every side mission on one character	All regions	A handful of side quests only appear during narrow windows in the story

The practical rule: after every story mission, walk the whole map before you fast-travel out, and check Sanctuary for Mamaril on the same trip.

Which character to run your completion on

Class skill achievements are per-class, so a full 50 requires starting all five characters — but each one only needs to reach the level where the skill unlocks, which is a couple of hours, not a full playthrough. The decision below is about the one character you take to 100%.

Your situation	Pick	Why it suits the list	Main trade-off
Solo, first completion run, want the least effort	Axton (Commando)	The Sabre turret earns its own class achievement passively and draws fire while you explore	Lower raw damage than a Gunzerker at the same level
Solo, want the fastest kill speed for the grind	Salvador (Gunzerker)	Gunzerking doubles your output, and the 90-second Gunzerk requirement falls out of normal play	Gear-dependent; weak early
Regular co-op group	Maya (Siren)	Phaselock doubles as crowd control, and revives are common in a group anyway	Slower solo boss kills
You want the challenge achievements to feel deliberate	Zer0 (Assassin)	Decepti0n rewards patient, aimed play that suits long-range sniper challenges	Squishiest of the five while learning
You prefer pets and passive clearing	Gaige (Mechromancer)	Deathtrap clears mobs while you focus on map discovery	Anarchy stacks punish dying

A practical completion route, in order

A completion route is simply the order that lets each achievement’s prerequisite already be true when you go for it. Following the wrong order does not lock you out of the Platinum, but it can add twenty hours of backtracking.
