I was thinking about this today. Since we have threads spead out on each of the maps that have been shown already. I thought to make a thread with every map shown so far and post a link so those who haven’t seen it, can see it. I’ll update the OP with a link to all the maps that come out as IGN releases them.
Gamespot Forge Preview, Impact, Erosion, Ravine
IGN Flood Mode walkthrough/partial Solace walkthrough
IGN Ragnarok aka Valhalla walkthrough
Links will be provided as more maps become available.
