increase the amount of time it takes for a headspider to take over

[brojob]

i was in a firefight with a ling, and killed them but i slipped on motor oil and their headspider had sprouted and climbed down my throat. it took not even 10 seconds for the ling to completely assume control of my body, and i had died. it really kills any kind of suspense of you having a foreign body inside of you due to the minuscule amount of time it takes for the ling to take over. i feel like it should at least take 30 seconds if not a minute.
