Patch Notes of Xeno Arena – Version 6.3

Holo-Arena and Creature Battles

Turn-based, tactical creature battles with brand new music, visual effects, cinematic camera angles, and combat protocols have been added.
Players with adopted creatures can now assemble their companions into combat teams and fight in simulated battles against creatures of alien life forms or other players.
Each creature has unique combat maneuvers influenced by its species and natural climate. Combat maneuvers include attacks, healing, stunning, shields, status effects, and more.
Creatures can dodge attacks in combat, perform bonus maneuvers, or land critical hits.
Companions gain experience in battles, gradually improving their combat abilities.
A new user interface allows for the modification of the genetics of your companion creatures and enables the enhancement of agility, health, and combat properties.
Multiplayer Holo-Arena tables have been added in the Space Anomaly, where players can challenge other travelers to creature battles.
Holo-Arena tables have been added to planetary outposts, planetary archive buildings, space stations, and some settlement buildings. There, players can challenge alien life forms to creature battles.
The alien life forms that participate in creature battles in the Holo-Arenas of the space stations are experienced system masters. They may be more challenging to defeat than planetary life forms but also offer higher rewards.
Victories in creature battles yield various rewards, including nanites, invitations to battles against alien life forms, and retrovirus pellets that can be used to enhance the combat properties of creature companions more efficiently.
