One thing that really hinders Evolve at the moment is the way in which news about the game is distributed to the public. Yesterday, I ran into a few people who had little or zero knowledge about the voodoo Goliath challenge. The same thing happened during the trapper challenge a while back.
I feel that a great way to get people up to date on Evolve would be to delete the main-menu newsfeed and create an in-game sub-menu specifically for news. Every time a new article appears on the sub-menu players could be prompted by a notification on the main menu with messages like “Something new appeared on the feed!” or “New Skin Challenge available, Check it out!”
I think this could really help players keep within the loop, because the only person in my circle of friends who hears about the challenges first is usually me.
