OpenLieroX for macOS
Play real-time 2D worm battles with OpenLieroX for Mac, with local bot matches, Internet/LAN multiplayer, custom maps and a built-in level editor.
What is OpenLieroX?
OpenLieroX is a real-time 2D shooter based on Liero Xtreme, with gameplay inspired by Liero and Worms. It suits players who want worm battles against bots or other people rather than a turn-based match. The publisher lists Internet and LAN multiplayer, customizable characters, weapon modifications and a built-in level editor. The base download includes skins, levels and weapon modifications; additional community packs are separate.
This entry links to the publisher's macOS ZIP for release 20260717.2, marked as a non-prerelease on GitHub. The publisher warns that this Mac build is not notarized and lacks an Apple Developer ID signature, so macOS can show an unidentified-developer warning on first launch. Download availability is verified by HEAD requests only; installation, gameplay and compatibility with a particular Mac have not been tested.
