Actually, the figure in the title screen is the moon. Jupix and I concluded it has to be.
Yes, we talked about this and the conclusion was that the scene in the main title screen takes place in space, en route to the Moon.

The alarm light model and door (possibly an airlock) have a feel to them very similar to the first level (which takes place aboard the freighter). The Silencer is looking out of a window, at the Moon, which is also visible in the picture as a reflection in the window. The rest of the space the Silencer is in is quite difficult to make out so that leaves some artistic freedom.
Further about the main menu screen itself, I'm going to do it personally. What I have in mind is a Source-esque background map menu, which means there is actually going to be a live scene running behind the menu items, just like in Half-Life 2 and all the other mods based on it. In my vision I have the Silencer standing in front of the window, just as he is in the original picture, but he is actually moving slightly, from heavy breathing. The moon will rotate in the reflection, and the alarm light will naturally be live. Also, there is going to be a soundscape of some sort, but I've yet to make a decision whether it'll be ambient sounds only or the original menu music only.
However as we don't have a sufficiently detailed Silencer model yet, this is all far in the future.
