Stage 1: Aurora

Mountain acts as a back up trigger for Aurora triggers

Stage 2: is from trying to turn off the Gun and failing

Going to the lost River is the back up trigger

This stage causes Warpers to become hostile

Stage 3: using the terminal in the DRF

Back up trigger for this is entering the Lava zone.

This stage causes the green spots.

"Stage 4": using enzyme 42

No back up trigger

Kharaa is completely gone and side effects are removed. This is consider a stage ingame.

Because of this. You cant possibly finished the game without being infected unless you are hacking or glitching.
