the models of humans seem to be going good, and the aliens models?
I believe that the models of the aliens need some adjustments(exemple: they do not move your head,attack only in one direction, walk and some others animations), and if possible, it would be interesting if the aliens had an appearance more silimar monsters, the models of the human will have a good improvement, I think that the aliens could not stay out.
the community could even help in the creation of new models.
one question> building models will be improved?
