PSA: Dead Nation Patch Out
A 35 MB patch for Dead Nation is now live on PSN. We believe this fixes the max friend list freezing issues, but it could very well add in voice chat for online.
Going to contact Sony and see what is added in this.
In the mean time check out our Dead Nation review!
Update: Doesn’t look like voice chat support is added. I just tested it out in a few games.
Update 2: Sony has confirmed via Twitter that this patch fixes the 100 Friends issue.
