MM2 Aim Trainer Blu, groups, and credits
Who built the range, why there are two places, and how to move old kills without guessing.
MM2 Aim Trainer is a fan range, not a Nikilis product. The person behind both live places is Blu, known on YouTube as livingblu and on the successor place as holderblu. This hub is the people page: creator, groups, credits, Discord, and the data-transfer steps. Official URLs sit on official links. Patch history sits on updates. First-session setup sits on getting started.
Blu, livingblu, and holderblu
Blu is one creator using more than one Roblox identity because the original place and the successor sit on different accounts and groups. livingblu is the YouTube and public face. holderblu owns MM2 Aim Trainer 2. The Roblox profile commonly linked from Blu’s videos is users/8374530594. Socials: YouTube @livingblu, TikTok @mm2.blu and @playmm2trainer.
Blu’s videos are the reason most players found the range. The home trailer on this wiki is the switch announcement. Do not expect Nikilis, Zyleak, or Thexz to answer trainer tickets. They are credited, not staff.
Two groups, two places
| Place | Group | Creator face | Place ID | Universe | Since | Scale |
|---|---|---|---|---|---|---|
| MM2 Aim Trainer | blu’s buds | livingblu | 6924758805 | 2647834887 | 8 June 2021 | ~897M visits, ~20.6M favorites |
| MM2 Aim Trainer 2 | b1uu | holderblu | 135193469413243 | 8160348242 | successor | ~180M visits, ~4M favorites |
blu’s buds is the original group. b1uu is the successor group (communities/36075047). Codes, Shop, and newer seasonal quests live on Aim Trainer 2. Cursor ID culture and the huge visit count still live on the original. Blu wants players on the successor. If Aim Trainer 2 fails to load, the original is the fallback, not a second homework assignment.
Premium cosmetics on the original include Icecrusher and Icepiercer. They are collection, not a different hitbox. Do not buy them expecting a better Sheriff shot. The shot comes from dummy work on the tier list.
Why a successor exists
The short version: Blu lost the ability to keep updating the original the way a live game needs, and built Aim Trainer 2 under a group and account that could ship again. The original still runs and still has millions of favorites. The last notable original update sat around April 2025. Seasonal 2024–2026 hunts, Shop codes, and the Surfer quest landed on the successor. That is why this wiki treats Aim Trainer 2 as the live place and the 2021 trainer as the archive that still works.
You do not need both inventories. You need one range, a readable cursor, and the dummy ladder. Switching is a Blu request, not a Roblox requirement. If your friends only load the original, you can still run the same dummy types. The updates hub tracks which place received the last seasonal drop.
Credits (not the same as ownership)
Aim Trainer 2’s description lists the people the maps and guns actually belong to:
- Nikilis — Murder Mystery 2, the game you are training for.
- Zyleak and Thexz — maps you load in the range.
- IDontHaveAUse and Nikilis — weapons.
This wiki is also unofficial. We are not Blu, not blu’s buds, not b1uu, and not Nikilis. If a credit is wrong in a seasonal UI, believe the in-game description over a fan page.
Discord and data transfer
Blu opened kill transfers so people would actually switch. The invite is discord.com/invite/blu-1219172382208561223.
- Join the server.
- Open #support.
- Create a data transfer ticket.
- Staff tell you what screenshot or user ID they need.
- Wait. Do not spam a second ticket.
Blu has said transfers are aimed at newer players, not a full wipe-and-copy for every 2021 account. If your ticket is refused, your old kill count stays on the original. That is annoying. It is not a reason to stay on an unmaintained Shop. Keep training on Aim Trainer 2 either way.
Discord is also where seasonal quests and code drops get announced before they hit a wiki. Cross-check codes after a ping. Do not paste random “free knife” strings from strangers in DMs.
Cheaters, PVP, and who this range is for
Aim Trainer 2’s description is blunt: cheaters are permanently banned with no appeal. The scripts page lists hubs so you know what not to run. The range is solo NPC work with optional 1v1 PVP. It is not a crew lobby and it is not Murder Mystery 2. Real rounds still happen in Nikilis’s game after you finish a dummy block.
If you came here for a roster of MM2 killers, you are on the wrong hub. This category is the people who ship the trainer. For dummy personalities, use dummy types. For first load, use getting started.
Two trainers, one creator, and a Discord ticket queue. Treat Blu’s current place as home, keep the original as backup, and do not expect Nikilis to support either of them. The range exists so you miss fewer Sheriff shots, not so you collect a second inventory.

Aim Trainer 2, unless it is down. Then use the original. Getting started is the same dummy ladder on either place. Shop codes live on the successor — see codes.
