Don't hold your breath on an SDK.
this is why these games die a quick death. They fragment the map community by making your PAY for maps, so now, how much are you investing vs how much replay value will it have when dies because there are no mods?
look at avp2010 for example. Its dead.
I am sure a MOD person can take this game, and at least give the option for the alien to be in First Person. or maybe the game is just doomed as an alien in 3rd person forever.
ruins the experience of being able to play the alien in First Person for the last decade. now your force to play like you have a camera over your shoulder.
It totally kills it for aliens lovers everywhere.
its a money maker for them, a quick one, and the game sadly will die a quick death.
