Gusanos

					
Gusanos is an open-source clone of the DOS game Liero. It currently works on Windows and Linux.
In the game each player controls a small worm armed to the teeth and fights other worms in a destructible battleground. It can be described as "Real-time Worms" or "2D Quake", or a combination of both.
The gameplay is as close as possible to Liero's. Hardcore Liero players will feel at home. Newbies, on the other hand, may find the controls hard to dominate at first, but not less enjoyable. Practice makes perfect.
Gusanos improves greatly on what the original Liero left, adding modern graphics, audio and networking capabilites along with a myriad of other features.
En Gusanos engine is fully moddable. It achieves this in a Quake-like fashion, so that each mod lives in its own folder without messing with the core game files.
Moddability is present at every level, from graphics to game logic. Hardcore modders get full power with the LUA scripting language. You can use the engine to create an entirely new game (Total Conversion), or simply add a few imaginative weapons.

Gusanos is, of course, free of charge, free to distribute and free to modify.
