Albion Online which is developed by Sandbox Interactive, boot up their servers for the start of their summer alpha program at 12:00pm CET. Those who have purchased and become Legendary Founders will have instant access to the alpha.
Some new additions to the game since the previous alpha are hell dungeons, up to 4 factions can do missions and groups larger than 5 now appear on the game mini-map for easier viewing.
