Title: OpenLieroX
1. Languages: English
2. Compatibility: I think all Windows versions since Windows 98
3. License: LGPL
4. Description: The Addictive 2D Shooter - Based on Liero gameplay, OpenLierox is an extremely addictive realtime worms shoot-em-up backed by an active gamers community. Dozens of levels and mods are available to provide endless gaming pleasure.
5. Opinion: It’s great to play that game in multiplayer mode against opponents from all over the world using several mods, levels and skins, and interacting with other users through game chat.

Edit (2012-01-16):
I "portabilized" the application, modifying a configuration file, so all app files are in App folder and all user data is in Data folder, like any LiberKey app. I could not make the *LKL.exe file, but I think this work is yours if you put that in LiberKey Catalog:

So, the portable app of the last stable version is here (documentation about that is in the page description):
