As a standalone expansion to the classic puzzle-strategy title, Oh No! More Lemmings (1991) offers 100 new levels playable without the base game. You guide hordes of small workers, assigning skills like digging or blocking to navigate hazards and reach the exit. This version features updated graphics and music while retaining the core loop of methodical, urgent problem-solving across intricate new stage designs.
This release is classified specifically as a standalone expansion, meaning it is playable without requiring ownership of the original Lemmings game. It was initially launched for classic computing platforms including the Acorn Archimedes, Amiga, and Atari ST/STE systems.
The primary appeal of this expansion lies in its significant addition of new material relative to its predecessor. It introduces 100 brand new levels designed to test the player's strategic thinking and timing.
To complement these new challenges, the game features entirely new graphics and music, providing a refreshed aesthetic experience while maintaining the established atmosphere of frantic, yet methodical, puzzle-solving.
The fundamental gameplay remains rooted in assigning specific jobs—such as blocking, building, digging, or climbing—to individual Lemmings to clear a path through the stage. Success hinges on the careful allocation of these limited abilities to ensure the required number of survivors reach the goal portal.
While adhering strictly to the beloved core mechanics, the 100 new stages present novel environmental puzzles and scenarios that demand creative and precise application of the available skills. The scope of this content is substantial, offering a complete, self-contained experience.
As an expansion, this title exists within the same universe as the original, continuing the theme of managing the fate of the small, often suicidal, creatures. It builds upon the established lore and mechanics without introducing major narrative shifts.
While the original 1991 version remains the definitive experience for its initial platforms, this title has received at least one known remaster, updating the experience for contemporary systems. This ensures that the core puzzle experience remains accessible to modern audiences, even though the game itself is a classic title.

This port of Oh No! More Lemmings sees the resolution noticeably increase compared to the original, which can be very obvious when viewing the lemming sprites. The soundtrack also gets clearer and in better quality overall.

The DOS port of this game is mostly the same graphically compared to the original Amiga release, though there are some slight color changes (most notably in the UI which has changed from organe to yellow). The original AdLib (and by extension, Tandy 3-Voice) tracks are generally longer than the Amiga arrangement, and they play in a slightly different order. The track "The smiling blues" plays before "Much joviality" and "Not at all serious". This game was released as a stand-alone expansion or an add-on, and could picked up either as a 3.5" or 5.25" floppy disk.
