Borderlands 3

You will unlock this after defeating the first boss in the game (Shiv) and releasing Claptrap (once you free him, stand next to him and hold X to revive him).

You'll first find slot machines at Moxxi's on Sanctuary, although there are a few others around the game too.

Drops are random - so just keep playing until you get a live grenade drop.

The cost of each spin increases with your level, so its not necessarily beneficial to wait until late game to try this.   Although, there's a lot of cash to collect in the Handsome Jackpot DLC, so after doing that might be a good time.

Moxxi is in Sanctuary and you'll have to visit her as part of the story. The tip jar is on the bar. It doesn't matter how much you give.

Use a golden key.  This can be done at the huge gnarly chest on Sanctuary.

You'll need an active SHiFT account (see the in game menus) - and to use it to redeem SHiFT codes for golden keys.  Google and follow BL3 on Twitter to get codes.

Using a key to open the chest will net you a bunch of purple/gold weapons and equipment.

There are 30 altogether.  You'll spot them as you go through the game and they'll have a bright triangular icon on your map.

However you cannot decipher them until near the end of the story when you gain a specific ability to do so.   Then you'll have to go back to them all (locations guide coming soon) and interact with each one - its worth 25 Eridium apiece!

Discover all named locations on Nekrotafeyo.

You don't get to this planet until much later in the story.

These are like horde mode challenges, with 5 rounds of enemies each with multiple waves.  Complete all three for the achievement.

You'll get this for completing all the main missions in the DLC.

You can start the DLC by reading a poster outside Moxxi's on Sanctuary.

You'll see these on the minimap as you progress through the Handsome Jackpot missions; they appear as small diamond-boxed grenade-like icons.  They all appear on the map well in advance of you getting close to them so they are hard to miss.

When you physically get close, Mr Torgue will speak and say something rowdy as only he can...

Hit each bottle of sauce to explode it and get the achievement.

They will mostly require some jumping/acrobatics to get to - but nothing too hard.

You can revisit areas after completing the DLC if you miss any; scout on the map to spot them.

During the Moxxi Handsome Jackpot DLC, there'll be a point where a claptrap gets 'stuck'. Just come back to the same point anytime after and talk to get the achievement. You can still do this after completing the DLC. Its in the Compactor level, due north from the central fast travel point right at the top.

Through the Handsome Jackpot DLC you'll encounter some fancy chests with a robotic voice as you approach.  To open them, 'cards' are drawn onto the front, keep drawing to get close to a total of 21 (king/queen/jack = 10).

If you go bust (exceed 21) you'll get nothing special from the chest.

Make sure to open every chest you find and this should pop sooner or later.  Some chests are in the VIP areas which you'll need to pay to enter.

If you miss them, you can revisit again later to try again.

This is a Challenge in the Moxxi's Handsome Jackpot DLC - to collect 5 pieces of the mayor's outfit.

Finish the "Sisterly Love" mission first, then in the central Spendopticon area, just south of the main part there's a random spawn area; it'll spawn on of an Ice Loader, a Shock Loader, a Hot Loader or a Debt Collector.  You may need to quit/reload multiple times to get the Debt Collector to spawn.  It'll be a big one, walking about on its own.

Once it does, kill it...

You can get these rare spawn missions to kill specific named enemies from the Lodge, upstairs.  But kills are still eligible whether you pick up the mission or not, so when you find the creatures along the way (you are exploring every area along the way right?) then take them out and you may get this just naturally.

There are various fish around the DLC - they talk and tell a joke and spit out some weapons afterwards.  Listen to 25 for the achievement.  There aren't actually 25 fish so may need to save-scum a little - but this also means you haven't got to find them all; you can just scum the one in the lodge repeatedly...

...and the easiest way to do this is just to do the fish every time you go back there through the DLC (and after finishing the DLC) and you'll get there soon enough.

Deathtrap appears on three separate occassions during the DLC.  Just stand back and let him kill.  you can weaken enemies `- but deathtrap must land the killing shot.

If you miss this, go back to Xenocardiac Containment and redo the Empowered Grawn boss battle - Deathtrap will be there for that...

Also, progress is profile-wide (not per character) so you can continue with  fresh character if you want.

Complete mission “Blood from a Stone”

Complete mission “The Name of the Law”

Complete mission “Off the Rails”

Complete mission “Where It All Started”

Complete mission “Riding to Ruin”

Complete all side missions on Gehenna.

Complete all crew challenges on Gehenna.

Complete all plot missions, side missions, and crew challenges on Gehenna.

Some reports of this being glitchy.  It'll be fixed - or may have already been - so don't panic too much.

You get heads/skins (rarely) as random drops - or from the slot machines at Moxxi's, or you can by them from Crazy Earl in the basement of Sanctuary.  If you're buying them this will help toward My Name Is Earl too.

Hold the action button over another (human!) player once they've been downed.

It helps to use the safe in Sanctuary to store items for this so you don't have to carry them around all the time. I.e. it doesn't matter what level or how good the items are - only their colour.

Note the 4th weapon slot only becomes available after completing the story mission "Beneath the Meridian", and the artifact slot only after "Cold as the Grave" (which is much later).  You therefore can't get this achievement until after that point...

50 is the level cap for the base game, but since raised with the DLCs.  If you're doing the full game and all side missions and the DLCs you shouldn't have too much trouble getting to level 50.  Plus then there's Mayhem mode and TVHM also...

You'll get a few of these naturally through completing the story and side missions.

Otherwise, for each new/different type of vehicle you hijack and bring back to a vehicle spawning station you'll get new parts.  Keep doing this.  It has to be a vehicle you haven't brought back before (but different variations of the same base type of vehicle do count).

Fairly easy; just do what it says on the tin.  It helps ofc to keep an eye out for sticky grenade mods early on and just keep equipped while playing generally so that you're ready to take advantage of a situation with enemies close together as soon as one arises.

You need to get 100 kills with a weapon from each manufacturer - you'll know when this happens as you'll get an notification of mail from the manufacturer which you can access through the social menu.

One easy way to keep track is to not use/delete those mails; save them up so you can see which manufacturers you've done it for.

The firing range is downstairs on the Sanctuary.
