Although the term "private test" may have been somewhat confusing, we can for certain say that the Closed Beta testing phase of The Mummy Online has officially started. Bigpoint has announced that they are now accepting any and all registrations to participate in the Closed Beta.
If you are interested in participating in the Closed Beta test, you can head over The Mummy Online homepage and sing up there. If you are selected to be a part of the test, you will receive an email with instructions and a code!
The Mummy Online is a free-to-play, browser-based MMORPG which takes you into the universe of the blockbuster movie series. Choose a side and uncover the mysteries of ancient Egypt as you explore tombs!
