Gathering a group of four people (including me) to systematically farm for shells. If you want to join in, just add me in game (GeoCritical).
We'll be going solo into the most efficient gate for getting Infernal Tunnels. If anyone finds the special danger room, he/she will invite everyone to the party.
We'll also be sharing the ID cards between the group, taking turns unlocking the portal.

If you need more info, just post below (I sometimes forget things).

Note: Defender Elite (those who have at least some 5*'s) to Vanguard only please.
