I don't know anything really about scripts, but is there one that will make the one that is infected and killed turn back to life as an infected marine or elite and the infection form disappears so it would look like it went into the body. Like in halo 3. (I got this idea from another forum.) I think "CPU Terminator" :)

Yes, but it's unfeasible to make it work for everyone. The script is recommended only for cutscenes, but for actual real time infection throughout the game, that would be unfeasible.

Im not sure what unfeasible means, but would it be POSSIBLE to do it in game too?

EDIT: Or is there a way in guerilla?

Dude same question, but all I want to know is how to make them infect? With or without the infection form disappearing...

It is possible to animate a biped to 'rise from the dead' in a cutscene, and animate the infection form to enter the other biped and disappear, but this has to be in a controlled ingame environment rigged with trigger volumes and such. Additionally, the amount of animation work needed to be done is tremendous.

In actual gameplay, it would be impossible in the current engine to have an AI actor walk into another and to have that other shift forms and rise.
