Ancient Chinese Secret

"I'm a weapons expert and even I have no idea what pistol this is supposed to be...And I have enough secrets already."

- Sergeant Ancient Chinese Secret is a minor easter egg found in the map Guilin Peaks. When completed, players will be given access to the Unknown Chinese Pistol. It can be completed on both solo or co-op play.

Step 1
In the middle of the Water Supply area, there is a noticeably shallow area that looks like a dried up mud puddle. Player(s) must use the China Lake grenade launcher on the middle area and it will open a small hole with dirt underneath.

Step 2
Player(s) must then obtain the Mini-Dao melee weapon and knife the hole several times until it eventually uncovers the pistol. It can be picked up and used for free for the rest of the game, but will only have one clip of ammo. The only way to get more ammo is to get a Max Ammo power-up or obtain it from the Mystery Box.

Trivia

 * The name of the minor easter egg comes from a quote from the 1997 video game Shadow Warrior, when the player's character finds a secret area.
 * When completed for the first time, players will unlock the achievement "Secret No More".
