What i understand that
it is possible but not with all mods
Thanks for the Reply.

I loved The mods in MW3 but the problem that it only works when joining the server
but i was a main offline player like, i was just playing with bots,
So my question here,
is there any way to play those mods with bots only? +i already have bots warfare

!!! The mods i mean (Arcane Snipers - Ice Snipers)

I wants a sliding mod out of dolphin just, and ur the only one who i can trust because of the great work
Please make us one, i mean think about it twice, if we got sliding on a perfect game like bo2
And dont worry
I only play the game offline, so i dont care if i destroyed my bo2 files
And i hope ur still working on origins
And thats all for the best legend here.
