This one came in late, would have been good for last weeks scary night. Splicers aka Aggressors, are Bioshock's main enemies throughout most of the game. They wear Masquerade Ball masks to hide their disfigured face. There are many types of masks that can be seen including rabbit, bird, butterfly, cat, and spider - this one has all of those. Thanks to liv for sending this in.
