Many of CRASHLAND's creatures are animated using procedural animation. This where AI is used to generate more interesting organic behaviour. Some creatures like the Hellworms and Longlegs are 100% procedurally animated, while others become procedural in their (very dramatic) death throes.
Procedural animation helps to make every creature encounter in CRASHLAND unique. It also helps make the game highly gif-able! Here are some gifs from Crashland. All running on Oculus Quest!
