With the latest Aliens vs Spirits update to Anime Reborn, featuring iconic units from the anime Dandadan, a new level was also added to the game. This includes the new Ghost Tunnel Portal, which provides you with a new challenge as well as tons of rewards for clearing. But getting your hands on it can be tough. So, to help you with that, here's a guide on how to get the Ghost Tunnel portal in Anime Reborn.
Currently, the Ghost Tunnel portal can only be acquired as a drop reward from the Story Mode. Thankfully, the odds of getting it are relatively generous. Here are the exact details of this item:
As you can see, the Ghost Portal has a 1 in 5 chance of dropping every time you clear five waves in the Infinite mode of the Ghost Tunnel story map. Moreover, you can also get the Mythic character Okarun from clearing a Tier 1 Ghost Portal at a 0.75% chance.
