'Is Alive' is a modification for Diablo 2: Lord of Destruction. There are new recipes, new monsters, new monster abilities, new locations, new quests, end-game dungeon and the most important - the game is much more difficult. No new character skills, no new acts, no new characters, no new uniques, no new sets, no new runewords. 'Is Alive' isn't a total conversion mod, and it never will be. The mod can be downloaded as D2SE modplugin. Extract the file and the folder 'IsAlive' just copy into 'MODS' folder in your Diablo 2 folder :) Enjoy ;)
