It's the tasty treat of mystery meat! In the world of Rust you eat what you can scrounge up, whether it be be radioactive bear, mangy wolf, or that guy who moved his base too close to yours. Slap on some processed cheese, a little green stuff, and some onions on a sesame seed (well, at least I HOPE those are sesame seeds) bun, and you've got a meal fit for a king. Also it does a fine job of smashing rocks!
