Twister

"The Twisters seem to be sentient - these storms chase you ."

- Rossby Bjerknes, CU Meteorologist

Locations
Twisters can be encountered on several arid, lava or ice planets. Including the Burrow.

Appearance and behavior
Depending on the planet ice, sand or fire twisters can be encountered. They appear as red dots on the scanner.

Twisters will remain stationary until someone enters their range of perception. Then they will start to move towards the player until they engulf them. Being inside the Twister deals damage to the player for as long as they remain there. Since they move slowly, Twisters can be outrun easily in most cases.

What Twisters actually are is not yet clear. They could be a swarm of small animals or nano bots that either coordinate via a hive mind or individually via flocking behavior. How they inflict damage is also unclear.

Twisters can be easily killed by grenades. Normal guns work too but they take many shots.

Missions
Several Fluffy Biscuit delivery missions feature sand Twisters as obstacles.
