On the level Halo, you can make Johnson a flood. To do that, you have to keep Johnson alive.

After you keep him alive, wait for the little floodlings to appear. Then, you kill Johnson.
You wait until the floodlings attack, they should notice the dead body and take over him.
Thats how you make Johnson as a Flood.
Though, he looks like a ordinary flood.
Enjoy!
