Does anyone know if there is a patch or mod of such a thing? also what do you think of this game? (some love it, others hate it)

Do you mean single player Co op? Or a multiplayer mod?

I cant play the game now, i dont really like it :P but when it first came out, i played it relgiously.

After trying a few mods...i became addicted to trying and having as many mods as i could...which eventually spoiled the game for me. I cant play the game with mods, but the mods ruin the game...

ah well

Yea, im looking for a Multi player co op mode, or something like that
