Mission 4: Secret mini-game
There is a secret mini-game that has Starship items. The entrance counts for a secret credit. Go to where you pick up the "Attrexian Arc Launcher". Shoot the wall at the end of the room (faced when you first enter the vault). A Super Mario Brothers pipe will appear. If you are having problems finding it, use the structural integrity view on your Tricorder. The controls are still the same, but it can be a bit confusing. If you fall off a ledge, you will exit the mini-game, but not die. You can re-enter the pipe at any time.
