I brought a version of the wallpaper pic up in a comment on cobra's channel, but is no-one examining that astronaut? Getting a good look at him, his helmet doesn't look fully enclosed: It's like a construction helmet, or maybe a mining one, with goggles hanging off of the front. His suit doesn't look enclosed, either. It's almost like a firefighter's uniform, with what looks like a hood. His backpack isn't connected to any air hoses, but it's got some kind of indicator on the back. Maybe that's storage capacity? I know that this is concept art, and likely isn't final, but I still feel some analysis is called for.
Changed it on my phone and put it in the laptops gallery of changing backgrounds
And graystone I don't really think there's any use really analyzing this. It's just art. I don't even think you can actually call it concept art. More like artistic rendering of an idea of what the game could look like.
