rule #2 in the r2da handbook states that whenever you run out of either

1. ammo

2. stamina

3. will to live

4. any combination of above

special zombie spawnrate will increase by 100%, and all special zombies spawned will be edgars/leapers if you are also alone while meeting above requirements; also all zombies will spawn near u regardless of how many other players there are somewhere else on the map
