"These screenshots still contain a lot of work in progress content. Any content that is used from Half-Life 2 is there temporarily until ours can be created and implemented. The Marine model does not yet have the customization system enabled, so the appearance will vary more once that is complete. We are aware of any visual bugs or issues, such as lighting of models or player shadows, and we are continuing to sort out as many bugs as possible (some have already been resolved since these shots were taken!). Everything you see will be improved upon."
The team are still looking for environment modellers/skinners, player animators and texture artists, so why not drop by their contacts page and aid the war efforts! You can also check out the rest of the media update at their site.
I hope to god it wasnt made to look realistic tho
