Hey guys, after watching this clip it seems that we have confirmed two birds with one stone.
The remake map Ragnarok, is undoubtedly the Valhalla map from H3. Also you can see the Mantis (Mech) stomping around in multiplayer. I am very excited about both of these tid bits. I know many people wanted to see Sandtrap back, but hopefully Ragnarok will satisfy you.
The clip is short/low quality, but it proves the point.
