“Dark Nexus Arena is in development here at Whitebox Interactive by a dedicated group of Warhammer 40,000 fans. Our vision is to adapt a never-before-seen piece of the Warhammer 40,000 universe to a videogame set against the brutal and bloody Dark Eldar Arenas. To that end we are calling on you, the community, to help us. Your feedback will drive our work towards game balance, bug fixes and development of the best Warhammer 40,000 multiplayer battle arena experience.
We want to hear from you, register on our Official Forum!”
