So which one is it?

There is one called assault mod, but it doesn't seem to have the Single player maps.

But i also found this one named Co-op Mod BETA v2, which has a link to file actually named coopmodav8.2. Unfortunatelly the developers site is dead.

Now that is also a name of another mod that is supposedly working (but lags a bit). Far Cry Co-op Mod v8.2


I am not sure though if this os one and the same thing.

Still has anyone have any experience with Far Cry co-op? i mean real single player maps played in co-op, notz additional maps?
