A Note on Bugs
While ARBO: Arena Tactics is more fleshed-out and polished than ever, it’s still in active development — some features may be unrefined or missing final VFX/SFX. Your feedback is incredibly valuable to us, so please share your thoughts on our Discord or in our user survey.
Creating this game has been an unpredictable but deeply rewarding journey, and we can’t wait to share the progress with you. Whether you’re brawling in Classic PvP or experimenting with the Prompt Battler, we hope you’ll enjoy exploring our fractured galaxy and discovering new ways to ascend beyond your wildest dreams.
See you in battle!
