Simultaneously - a somewhat separate community evolved in southern Poland with the prominent clan “Liga Liero”. This new breed of editors could penetrate much deeper into the Liero game files and allowed editing weapons, changing the palettes, and altering of the physics of the game. Participation spiked and several new editors saw the light of day, with the most groundbreaking of them all, LieroKit and LieroHacker by Gliptic (Erik Lindroos). In the following years, the community moved off the guestbooks and message boards into the new heart of the community - The LieroNet Forum. The community began to blossom on the Wormhole guestbook page. The core of the site was the Liero editor Wormhole which let you convert BMP files into Liero levels, the Liero Blood Increaser which could set the blood spray all the way up to 32750%, and the Liero Graphic Editor which allowed users to create custom skins for the worms and projectiles.
The one which was to become the foundation of the community was "Wormhole - The Ultimate Liero Level Editor". By this time a multitude of fan sites for Liero had already cropped up on the world wide web. Development stopped in January 2000 at the final version '1.33'. In 1999, Joosa became disillusioned with game development and decided to retire the game. It soon began spreading on the internet, particularly interesting the owners of low-end computers. It quickly became a popular pastime in Finland and even won some “game of the week” awards. The game was first published in 1998, in the Finnish "mbit" computer game magazine by Joosa Riekkinen. Liero - originally envisioned to be a top-down-view game - eventually came out as a clone of MoleZ, a similar subterranean shooter game featuring moles instead of worms.
