Alien Vs. Dead Space, by Vitor Zago at DeviantArt. Very cool. I’m currently in Dead Space mania, thanks to Dead Space 2, the Dead Space iPhone game, the PS3 (re: hi-res) version of Dead Space Extraction, and the new animated Dead Space movie all hitting me at the same time.
In space, no one can hear you curb-stomp their head like a watermelon.
BTW, I like Isaac, but the Alien would win.
