Arbastro

Arbastro is a Roblox development studio and company that creates software, games, tools, and digital experiences. It operates under the main Arbastro brand plus subsidiaries arbastro Labs (game development) and arbastro Systems (tools/infrastructure).

The studio is best known for Expedition Rubasa, a nature/survival/adventure experience set in an Alaskan rainforest-style trail (inspired by Expedition Antarctica). Players navigate hazardous terrain toward Valdez with mechanics including hydration, food, sleeping, vehicles, and roleplay tools. The game has received major updates, including a full recode, performance improvements, and new content, and has recorded millions of visits.

Beyond games, Arbastro publishes open-source Roblox modules (e.g., task schedulers, spatial queries), web tools such as FriendPath (a friend-path finder between Roblox users), and supports other developers and communities. It rebranded from AnkOrange Studioz to Arbastro in December 2023 after a co-founder’s departure.

The studio maintains an official website (arbastro.com), Roblox groups, Discord, and social channels, and lists collaborations with various developers and platforms.
