Euro closed beta tests begin on February 17th, and you can either take your chances by registering on the game's official website, or pre-order and get guaranteed access to all five events. Pre-ordering also gives you head-start access on May 3rd, name reservation privileges, and various special items depending on your retailer of choice.
The retail collector's edition features the game soundtrack, a world map, an art book, and more, and you can learn all about it at TERA's European website.
