As someone who grew up mainly playing the MacOS version of Lemmings, thank you for all of your effort!    Yes, the graphics did indeed seem better on Mac. But I could never quite put my finger on what made the difference.

MacOS 13 (Ventura) is already the latest OS my current 2018 iMac supports, though, so I don't know how long I will be able to run this (assuming the hardware demands for even a remade Lemmings game aren't so high that an iMac from 2018 with fully upgraded 64 GB of RAM wouldn't be able to run it).

It is possible to create levels for Lemmings 2: The Tribes itself, but then you have to swap the original level files out for your custom ones to play them. Also, you will be stuck with the L2 engine and all its execution-difficulty problems when it comes to using the Fan tool etc. And skills like the Fencer and the Stacker will behave as usual in Lemmings 2, not as in NeoLemmix.

Okay, some big news!

First of all apologies for the broken builds and bad cursors. The cursor is now back and better than ever! Colour changing four corner presicion reticule, with attached skill icon and lemmings counter. It prioritises the correct lemming going in the right direction, so far fewer punching the air or lost builders! This is an optional QoL, so you can turn it back to classic hard mode if you want.



Automated updates, so you won't have to come back here for new downloads! Though please come back and give feedback!



Level select with Cover Flow! Select any unlocked level, or unlock them all in settings!



Create and save playlists! From any level across any pack, even Lemmings 2 and Lemmings 3 - or the 6000+ fan made levels. Want a random pack? Create a shuffled ten level pack, or just go endless shuffle across any or ALL packs!

Every. Single. Soundtrack. Across. Every. Single. Port! (Plus fan-remixes). This has blown out the package to 1.7Gb, so the next version will have these as optional downloads on launch or in settings (ala Logic soundpacks).

What else is new in Ultimate Lemmings 1.5.0 since 1.1 RC2?

Level browser and playlists

• A new CoverFlow browser shows campaigns, fan packs and individual levels with screenshot previews. Browse with the mouse, trackpad, keyboard or controller.
• Create and edit personal playlists, play them in order or shuffle them, and resume a saved playlist run.
• Generate a Random 10 playlist from a chosen pack, or shuffle the installed fan-level library without repeats within a run.
• Reduced Motion replaces the animated carousel with a stable thumbnail list.

Controls and targeting

• Original, Modern and Custom gameplay presets make it easier to choose your preferred controls.
• New targeting options favour blockers when assigning a bomb, and builders when extending a bridge. These apply across Classic, Lemmings 2 and Lemmings 3, using Use tool in Lemmings 3.
• The four-corner cursor shows green for an eligible target, yellow for an ineligible target and grey over empty terrain. Choose no skill icon, 1× or 2×, and optionally show the nearby lemming count.
• Target highlighting uses a subtle halo and shimmer, with a static halo under Reduced Motion.
• New toolbar buttons rewind two seconds or step one tick backward or forward. Play stays paused afterwards. Controls are disabled where the ruleset does not support them.
• Open hints with H, I, F1 or the toolbar. Left and Right move between hint stages. Revealing a full solution still asks for confirmation.
• New levels and retries start after a cancellable 3–2–1 countdown. Saved runs and Hot Seat handovers stay paused until the player is ready.
• Fast-forward now raises the music pitch without changing its tempo. Lemming trails grow longer and softer at higher speeds across all three games.

Soundtrack

• The expanded DJ catalogue contains 495 versions of 210 tunes, including Amiga modules, other ports, composer recordings and fan remixes.
• A tune starts with its original Amiga version. Later levels using that tune can play alternate versions. Retries, saved runs and Hot Seat handovers keep the same version.
• Music stays consistent during a level, with transitions at changes such as the result screen.
• Retry has a vinyl-style stop and spin-up effect.
• The Mac sound set now uses the Amiga pop sample. The SNES recording of "As Long As You Try Your Best" plays to the end.
• Bundled recordings use 192 kbps AAC to keep the download below 2 GB. Amiga modules retain their native playback.

Menus, performance and fixes

• Dialogs support Tab, Shift-Tab, arrow keys and Return. Replay and original-movie controls have keyboard and accessibility actions. Hot Seat handovers also accept keyboard input.
• The normal mouse pointer stays visible over menus and controls. Disappearing cursors in Lemmings 2 and Lemmings 3 are fixed.
• Startup and title-menu navigation are faster. In a test with 516 saved runs, finding the newest run fell from 6.1 seconds to 0.26 seconds.
• Returning to a campaign avoids repeated setup, transition saves no longer block play, and HDR work starts only when needed.
• Fixes cover pause-key repeats, speed-button toggles, clicks behind bridge builders, liquid beneath bridges, missing rescue targets and Classic hints, and the black window on a fresh installation.
• Signed update checks now start with the app. From 1.5, available updates show release notes and let you choose when to install.

NeoLemmix preview

NeoLemmix work improves level rendering and adds a reader for current .nxrp replay files. Full replay and gameplay compatibility remains unfinished. Fencer, Laserer, skill pickups and several other mechanics are still unsupported. Lemmings 2 and Lemmings 3 also remain previews.

Turn off prioritise builder in settings as it doesn't work as expected in this build (blocks other lemmings from being selectable whilst being unselectable themselves). This is fixed in the upcoming 1.6.0 build (below)

Quote from: Proxima on September 25, 2026, 05:56:38 PMNeoLemmix isn't getting any more skills. Namida has decided to stop further development of the original NL engine, and while WillLem is still developing NL Community Edition, it has to remain physics-compatible with original NL.

damn...

Pourer skills would probably require new extra physics, much like the Jumper took long to implement because of tumbler physics.

SuperLemmix has the Grenader instead of the Bazooker. It was originally introduced briefly in NeoLemmix proper as a test skill, and then it was ultimately decided not to add it to the stable release of NeoLemmix. As of right now, I still have a commemoration line for that era under my profile picture.

So, just a brief question almost two years later: How final are the SuperLemmix physics at this stage?
Because them not being finalised yet at the time was why I stopped working on my official conversion of Lemmings World Tour for SuperLemmix around the Professional rank.

(I understand that, in the meantime, SuperLemmix levels have received their own file format, so converting the pack now seems like a lot more additional effort on top of adapting all the solutions to having Freezers instead of Stoners, and considering all the changed physics).

NeoLemmix isn't getting any more skills. Namida has decided to stop further development of the original NL engine, and while WillLem is still developing NL Community Edition, it has to remain physics-compatible with original NL.

You might be interested in looking into SuperLemmix instead; it's a fork of NeoLemmix that already has more features, including the Grenader (not quite a Bazooker, but it is a throwable explosive) and L2's Ballooner. Also, it's still in active development, and as far as I know, is still open to the possibility of more skills being added in the future.

However, please don't get your hopes up for any NeoLemmix or SuperLemmix-like engine that includes all the L2 skills. Coding all 50 skills would be a huge amount of work for very little benefit; the community widely agrees that L2 went overboard and there is simply no need for that many skills.

ok i know about those skills,

but what about the ones that are original like the bazooka and powders? (those ones il love to see them )

Some of the skills from Lemmings 2: The Tribes are usually deemed redundant by the NeoLemmix community. The Stomper, for example, is just a Digger with a different animation; the Scooper is a Miner with a slightly steeper angle, and so on.

Meanwhile, NeoLemmix has skills that cover design space that The Tribes did not address. The Fencer and Laserer in NeoLemmix, for example, are much more useful due to their steeper diagonal angle. The Laser Blaster in The Tribes is really only good for blasting the crowd out from below at the end; and the L2 Fencer moves up at such a low inclination that it's much closer to the Basher than the inverted Miner it is in NeoLemmix.

That's not even speaking of skills like the Cloner, Stoner / Freezer, and even the Disarmer, which don't have any approximation in Lemmings 2: The Tribes.
