Tread is the newest Quake/Quake2 map editor from IMRlabs. It is currently at it's first beta stage Beta1. We are trying to spread this editor to everyone because we feel it is a very competent and usefull tool. It will soon support HexenII and Half-Life. We wish to involve everyone in the free public testing of this editor. We here at IMRlabs have worked very hard to bring the gaming community this editor, and we hope that people enjoy making kick ass levels with it!

Thank you very much,

IMRlabs Team
