Thanks mate

Community Day head (and skin) is currently available via Shift code 5B3BJ-XZWFW-T3KRZ-JBJTB-6WST9 as part of the Borderlands 3 promotional stuff.

(Zer0 is 53KBB-KXXRC-RZ66Z-WFJBB-WSRZ3, and Salvador is C35TB-WS6ST-TXBRK-TTTJT-JJH6H, while you're at it.)

I heard that Closing Time is now a world drop. Never heard of it dropping.
You are missing the Goliath, which is given to players who bought the Diamond Plate Chest (or something like that).....it`s 100$.....was.

[Rhawn]

Thanks for the tips :D

[n0cta]

Both ^^

[Rhawn]

To get Admiral Asskick, do I have to kill the enemies while they are phaselocked or kill them with phaselock damage?

[n0cta]

Happy to serve my fellow steam users!

[Doctor Ellios]

Maya is my life
Thank you for this mister.

[Guz]

Well, for example, you added the T.K Baha head, from the first Head Hunter DLC, there are 5 HH DLC´s and each one of them gives you a head (TK Baha, Watter Gobler, Marcus Mercenary Day, Moxxi wedding massacre, Son of Crawmerax).

[n0cta]

Thanks, there are? This guid is a bit out-dated, tell me what I'm missing and I'll edit it and add you to contributors.
