I've been playing Horde on GOW 3 for the last few weeks & loving it! two days ago, was playing an on-line game on x-box live and during a Horde match I was suddenly unable to pick up weapons or purchase items. Game still plays, & resets my ammo after each wave. I'm unable to build fortifications tho, & the only thing I can do with cash earned is to give it to other players. Same with private games on my console only. I have two copies of the game (2 xboxes) and both work fine in my son's console, and he has no problem going on-line- game works normally for him. when we play system link horde, he has no issues, but my problems remain.
