Oasis is the fifth level in Serious Sam: The First Encounter and Serious Sam HD.


Sam must fight his way to the fourth, and final, element, which is located inside the temple near the oasis.


  1. From your starting position, turn back to find a secret ammo depot.
  2. Inside the temple, pick up the +1 health pill left of the statue. (picking up the one on the right will cause a Major Bio-mechanoid to spawn.)
  3. After picking up the health pill from #2, blow up the statue to activate a secret bouncer.
  4. After activating the secret bouncer in #3, it will give you a message about a secret doorway opening. Use the bouncer to be bounced to a secret Minigun.
  5. In the room with the Marsh Hopper fight, blow up the last wall to the left to reveal some health and Bullets.
  6. From #5, pick up ONLY the health bottle and exit the secret "cave". This will spawn an Arachnoid and register the secret.
