Tips
  • The Khnum is much easier than it looks; four cannonballs will kill it easily.
  • The Witch Bride can teleport and telekinetically lift you; try to shoot her as soon as you spot her.
  • The secret keys found in the shack do not count as a secret but are important later.
  • Be aware of a Gnaar attacking from behind after advancing past some Rocketeers.
