I'm a sucker for Asian horror. Nothing seems to scare the hell out of me more than Sadako from Ringu. That's probably one of the main reasons I was drawn to F.E.A.R. Alma is the official creepy mascot of the FPS shooter series. Her presence is always felt, even if she's not on screen.
In the first game, she appears as both a little girl and a naked, emaciated young woman. She pops up while you're climbing down a ladder or in a dark hallway. Sometimes, she leaves bloody footprints. She also tries to attack you. At the end of the game, you must escape the facility and Alma before it blows up. Later , when you think you're safe in the helicopter, Alma's hand reaches in and pulls herself up. Then the game ends. Alma is a big mystery. Who is she? Is she alive or dead? The answers are pretty shocking.
After being put into a coma and sealed in a vault at the age of seven, she was impregnated twice, once at 15 then again at 16. At the age of 26, she was taken off of life support and was declared dead. This is when one of her sons, Paxton, turned ten. She psychically linked her mind to his. She's able to "talk" to him and tell him to do things. Like in the first game, she tells Paxton to "kill them all." And of course, being dead doesn't stop her from psychically attacking everyone when the facility housing her was reopened.
In the second game, it ends with her forcing herself on your character, Michael Becket. She spends the third game pregnant, but still manages to terrorize. However, as you learn more of her back story, you kind of feel bad for her, especially in the third game. (Paxton's gross ending, for example)
Is Alma a monster? Yes, whether she's like that because she was born a monster or because of the experiments when she was a child. Maybe it's a mixture of both reasons. But, in the series and especially in the first game, she's freaking creepy.
