Super Skunk Gas, originally titled "Poison Gas", is a damaging gas which causes Animals inside of it to gradually lose health and kill them if their health fully depletes.
At certain preset times, Super Skunk Gas slowly advances from the edges of the map for a set amount of time, to the point that everything outside of the "Circle of Life" will be covered in the Gas. After the Super Skunk Gas stops spreading, the Circle of Life instantly shrinks and after some more time the Super Skunk Gas will start advancing again. Initially, it takes a hundred seconds to cover up the area outside the Circle of Life, but as the Circle of Life shrinks, so does the amount of time the Super Skunk Gas takes to cover up everything else outside of the Circle of Life. In addition, the Super Skunk Gas itself will incur more damage to Animals caught in the gas each time the Circle of Life shrinks, starting from minor increments of damage, and eventually culminating in dealing massive damage near its smallest size. This causes the area of the map in which Animals can survive in to shrink in order to force Animals to encounter other Animals in the map.
The Circle of Life is marked on the map on the HUD as a blue circle. When the Animal is outside the Circle of Life, an arrow will point towards the Circle of Life on the HUD, and a blue line to the Circle of Life is also drawn on the map, to assist in getting back inside the Circle of Life. The time remaining for the change in the size of the Circle of Life and the next time the Super Skunk Gas advances will also appear on the HUD.
A Skunk Bomb can be used to throw a small radius of Super Skunk Gas to potentially block off areas or damage enemies who move through it. This is independent of the Super Skunk Gas that normally advances to cover up the map, and in fact also does a different amount of damage to Animals who cross Super Skunk Gas created by a Skunk Bomb, as the Skunk Bomb does a fixed amount of damage per interval.
- v0.85.8 officially changes the designation from Poison Gas to Super Skunk Gas and named the safe area the Circle of Life.
- v0.86.1 added additional end-game circle to minimize chugging contests.
- v0.87.4 added Skunk Bombs which produce Super Skunk Gas.
