Predator: Concrete Jungle Cheats
How to beat Prototype Ulysses
Approach his back and press Jump when a symbol appears above the Ulysses head. The Predator will jump over the robot and kill it with a single blow. REMEMBER: This does not works with the gray Ulysses Prototypes with red lines.
Dead Men Walking Uncle Sam poster
In the Dead Men Walking level, you can see a poster of Uncle Sam on the sides of the Sanctuary.
No Predator sounds
Use the free camera and moves it down until you can see the Predator from below. If you make any movement (for example, use the War Cry, Voice Mimmicry, or the attack buttons), no sound can be heard. However, if you adjust the free-camera you will hear the sounds again.
Easy melee attack kills
Use the Wristblades, Glaive, or Maul. Lock on your prey. Approach next to the opponent and start walking around it while giving one blow, walk, give one blow, and walk.
