You are in the FBI base on a
deserted island, and the base receives an email threatening to destroy the
base. You trace the email to
You wake up from a knockout and the people
on the helicopter are setting up the gear they have as a sort of base on the
island. They send you out (since you are the best agent) to find out more about
the island. The game starts. You go out and see the people you followed here
murder someone. As you are running away you fall into a ditch and find something
that leaves more mysteries than it solves. There is something weird
about the island. You take the item back to your base, and the guys analyze it.
They send you out to find more artifacts and gather stuff, returning the items
to base.
As you get more artifacts, you can fight strange tree bosses and lava
monsters and access more of the island, also set up more bases in
different island districts.
Here is what the island might look like.
Another detailed run with a different possibility.
