The latest update to Rust has introduced a new rainforest biome that features dense vegetation and presents unique gameplay challenges, including predators like crocodiles and tigers. Facepunch Studios has warned players about the dangers in the jungle, emphasizing the need for vigilance due to potential ambushes. Players have found resource gathering more difficult due to the jungle's density. This update is part of a series of enhancements, including real-time food cooking, craftable pies, bee grenades, and a primitive mode with pre-industrial tools.
