Flood Infection

[Bulzome]

At some point I imagine the flood will be added in so I was wondering how will infection for the flood work will it be like in the games they can infect dead Humans or Covenant and sort of " reanimate" them or will it be like Colonial Marines or standard SS13 where if you get facehugged and someone does not pull it off you in time it will infect and eventually if you do not get surgery your character's chest will burst.
