You should aim to get all of these in your first playthrough. You can gain these at any point in the game, so please don't take the order I've listed them in as the correct order.
When you find a weapon with an elemental damage attachment (as stated previously in this walkthrough), you’ll need to kill 25 enemies with it. This is true for all four elements: Corrosive, Explosive, Incendiary and Shock.
FacemelterKilled 25 enemies with corrosive weapons
PyroKilled 25 enemies with incendiary weapons
As explained in the “Hints and Tips” section of this walkthrough, each class has a different Action Skill. You’ll need to kill 15 enemies with the Action Skill to gain the next four achievements. You cannot change your class during any given playthrough, so just start a new game with the relevant class, play through the storyline missions until you earn the Action Skill ability, and use it as and when you can. You only need to kill one enemy with the Phasewalk (the Siren's Action Skill) to gain the "Truly Outrageous" achievement.
Each time you kill an enemy using a weapon, whatever weapon group it belongs to, your proficiency for using that weapon increases. Use it for long enough and you’ll gain a level in that weapon's stats. Use it for even longer and you’ll get to level 10. You can check your weapon proficiency on the Character page in your in-game menu.
Make sure you mix up the weapons you use and don’t just stick to one gun, at least not until you’ve earned the “12 Days of Pandora” achievement. This is where you have to earn a specific number of kills with certain weapons, which are as follows:
12 kills with an Assault Rifle
11 kills with a Pistol
10 kills with a Shotgun
9 kills with a Sub-Machine Gun (SMG)
8 kills with a Sniper Rifle
7 kills using Melee
6 Critical Hits (mainly the head)
5 Explosive kills
4 Shock Kills
3 Incendiary kills
2 Corrosive kills
and 1 Grenade kill.
You can track your progress in the menu by scrolling over to the Challenges section.
You’ll come across Elemental Artifacts during the game which can be applied to your “Action Skill”. Again, the four elemental groups apply in the way of Corrosive, Explosive, Incendiary and Shock. The first artifact you’ll discover is after you complete the “Shock Crystal Harvest” mission at the Fyrestone Bounty Board, which will reward you with a Shock artifact. Simply apply it to your Action Skill in your Skill Tree and the achievement will unlock.
Class Mods are items that are found in Pandora that add extra stats to your character. They all differ in stats and can be very useful in combat situations. They are class-specific, so you cannot equip a Hunter Class Mod to a Soldier. As soon as you equip one, you’ll earn an achievement. The first instance you’ll encounter with a Class Mod is at the beginning of the game when you turn in your mission “Sledge: Battle for the Badlands” to Dr. Zed. Go into your inventory list and simply equip it. For those who are wondering what the achievement name means, it’s a line said by Tim the Enchanter in Monty Python and the Holy Grail. Cool huh?
There is an abundance of weapons in the game; an estimated 17 million odd, so selling 50 weapons to a vendor won’t cause you any problems whatsoever.
FenceSold 50 guns to a shop
A nod to “Slumdog Millionaire”, you’ll need to earn $1million to earn the following achievement. You’ll get this by finishing missions and selling weapons. Just be patient and in time it will unlock. You can see your progression in the Stats menu.
Within the game, you may have noticed certain Claptrap’s that need rescuing by way of retrieving Repair Kits. For every Claptrap you rescue, you will be rewarded with a Backpack Storage Device which will expand your inventory space by three. There are 10 Claptraps to find. Once you find the broken Claptrap, speak with him, then follow the waypoint marker to find the Repair Kit. Then simply return it to him. The location for each Claptrap is as follows:
Sledge’s Safe House
Clatrap Location: Follow the path until you come to a “Bunk” room and continue up the ramp ahead. Continue onwards and turn right instead of left and you’ll see him at the end of the corridor.

Then simply jump onto the beam and you’ll be there.

Claptrap Location: The Claptrap is located South of the vending machines, in a Bandit Camp. You’ll find him on the floor to the right of a washing machine.
