Konami Game Surprise:

Invisibility (Stealth/Camouflage Gear):

Pantless Meryl:
Follow Meryl into the women's bathroom & reach the last stall in under 5 seconds. Meryl will be caught with her pants down during a FMV sequence. Look in the vent just before the DARPA chief (Decoy Octopus) to see Meryl doing sit-ups. Leave the vent & re-enter & she will be doing 1 armed pushups. Repeat & she'll be doing leg stretches on the wall. Repeat again & she'll be doing the leg stretches pantless.

Look at Meryl with the scope or camera.

Hint: Box Destinations:
Equip a box while in the trucks to travel to the destination on the boxes.

Hint: Annoy Cambell:
Snipe the rats above where you 1st encounter Wolf. Or snipe the ravens when at your 2nd encounter with Raven.

Hint: Naomi & Cambell Pun:
Notice that Naomi & Cambell are on the same frequency? Also, Naomi Cambell is the name of a supermodel.

Hint: Defeating Psycho Mantis:
Plug the controller into port 2 & press any button before fighting Psycho Mantis. The word 'Hideo' will appear in the corner of a black screen. Use controller 2 to fight against him to keep him from knowing your moves. Alternatively, shoot the statues in the top corners with the fa-mas to render Psycho Mantis without his psychic abilities.

Hint: Seeing Through Psycho Mantis' Eyes:
Press Triangle while fighting Psycho Mantis to see through his eyes.

Hint: Open Some Doors Without A Key:
Use the guards to open doors. Just get them close enough to the door & they will open it. Down, Circle, Circle, Right.
