We've seen some pretty dope examples of futuristic military in movies like District 9 and yet-to-open Chappie.
I've just came from the movies, after I watched District 9. It was a true thrill to see such a great "low budget" film made and it only reminds me of how great sci-films were back then, and there was a total lack of good sci-fi films like that lately, until District 9 arrived.
Of course, if you've watched the trailer, you realize there's not much of space action, but the movie is great nevertheless. And as a little tribute to this movie, I've found this great concept arts by Alexey KaranaK, an illustration form Siberia. This guys really knows his deal, and he makes some sweet spaceships concepts! I've loved it. Fore more, you should visit his page at DeviantART, because it's really worth it! I hope you all like it! And go watch District 9, seriously. ;)
