Fullly played the first 2 missions, no problems really.
Played mission 3 for about 2 hours solo, but it crashed, was using the CSLA mod, which.. as far as I have expereinced is pretty unstable on my setup.
But yeah, this is UBER impressive as far as missions go, in fact this is defiantly the best coop I have pretty much ever playedin ofp. The GUI and in game communication with npc's its awesome.
In mission 3 I could not Put all the items in my vehicles to "dump" to the inventory, I'm probaly just an idoit.When i would return the vehicle itself to inventory and then bring it back all the objects would also be deleted, but I imagine thats pretty much unavoidable.
I may have a good chance to lan test this with about 4 others this weekend, I'll try to post some results if I remember.
Can't wait till this is outta beta, great stuff !
