Activision has released a new patch for United Offensive, bringing the Call of Duty expansion pack to v1.51b. The update resolves an exploit that can be used to crash servers and an issue with non-functioning MG’s on mp_bocage. This is a server side only patch - if you do not plan on hosting a server there is no need to download and install it.
