Resistance Global Servers and New Map Friday | PS3Blog.net
That’s right, Resistance finally changes to global servers on Friday 29th June and you will also be able to download map pack one. I got this info from the message screen when you go online on Resistance.
The servers will be down from around 2.30am Friday morning and will be down for most of the day. Once they are back online, you will be able to download the map pack one and you should have the option to choose between the EU/NA and Global servers. The time mentioned is for the UK so I have no idea of when the NA equivalent will take place.
EDIT: Map pack 1 will cost £2.99.
