Xeno Arena

Battle modes, league ladders, and exclusive reward eggs from the Xeno Arena system.

United by an enthusiasm for all things zoological and sharing a keen competitive streak, members of the Arena League roam the galaxy seeking new life to tame, nurture and train. Members can be found at Holo-Arenas on planets and Space Stations challenging one another to prove which of them has raised the most powerful, well-trained Companions in simulated battles between their creatures. They are always accepting of new challengers, though Travellers will have to prove themselves before they can expect to take on the toughest competitors.
