When you are underneath and you try to move the C-Stick up to look at Ashley, she will ask Leon what is he looking at and call him a pervert.

Killer7 Endorsement:
Later in the game, the Merchant has a gun called "Killer7". This powerful magnum shares the name of an upcoming title by Capcom called "Killer 7".

Hidden Trailers:
If you don't push any buttons at the title screen. Then after about a minute or so a never-before-seen trailer will play. If you do the same thing at the title screen after the 1st trailer has played then the trailer from The Tokyo Game Show of 2004 will play. It will play these 2 trailers for as many of times as you don't push any buttons at the title screen.

Title Screen Controls (for the Alternative Title Screen):
Use these controls during the title screen. C-stick moves the backround left and right. R zooms in backround. L zooms out backround.

Del Lago Secret:
When you first enter the area where you fight Del Lago, the monster in the water, head down to the dock. If you shoot the water about eight to fifteen times, you will get see what he thinks of you.

Alternate music in "Assignment Ada" credits:
After you watch the credits at the end of "Assignment Ada" it will ask you if you would like to watch the credits again. Choose "yes" and it will play the credits again but with different music.

Shooting Range Explosion:
During the Shooting range minigame, shoot 5 targets in a row without missing to unlock the Salazar target in the backgrund. Shoot it and an explosion will run through the area and give you 500 bonus points.

Leon does jet ski jump:
In the final area when Leon and Ashley are on the jet ski, if you press the L & R buttons and jump just before you do this, Leon will do a spin on the jet ski.

Extra Enemies:
This trick will summon cannon fodder your way. In the graveyard area, with the church where Ashley is actually held, there is a bell tower connected to the church (to its right). If you ring it, they will come. You can shoot it three times only. The first and second waves of enemies will come from the cave entrance and the third will come from the bridge area.

Free Ammo:
When you upgrade any weapon's capacity at a merchant, he will refill the magazine free of charge. This is very helpful with the magnum, or TMP

Still get money from dropping El gigante in lava:
After you drop one of the giants into the lava and kill the other one normally, leave the room and go back in and p15,000 will be in the center of the room.

Free Eggs:
At any location with chickens, you can sometimes find eggs. If you save nearby, then reset the game and reload your file, then run around in circles in an area with chickens, in about 1-5 minutes, more eggs will be laid! Free health if you ever need it! Best area to do this is the farm.

Get extra money and items:
At various points throughout the game, you will come across different animals such as crows and fish. These animals can be shot and will reveal different items or amounts of money to obtain.

Alternate Ada Scene:
After your second encouter with The Village Chief head straight back to the previous room where you met him. A scene will occur where Ada saves you from The Village Cheif again.

Get kicked by a cow:
During the 1st part of the game, after the village you will come a farm with many cows. If you knife a cow enough times it will kick you to very very low health, but IT WILL NOT KILL YOU!

Extra Scene With Luis:
During the part where Leon and Luis defend the cabin, shoot Luis with your pistol (or any other gun) around 8 or more times. You will get a cut scene where Luis will shoot Leon back, and give you a game over.

Ambush Congregation in the Castle for $$:
In the castle area, right after engaging the Bugs in the sewers, you will see a large group of Ganados Zealots in mid prayer. If you spook them they will run away, and you miss out on ALOT of money. Right before the sewer they give you a flash grenade. SAVE IT. When preparing the ambush on the congregation, go north then swing across the chandelier. When on the other side look down, and try to hit them all with a flash grenade to stun. Immediately jump down and run north to their exit point so you lock them in. If you have an incendiary or frag grenade you could use it here, other wise line them up for some shotgun carnage. They will each drop a spinel and their leader drops an Illuminados pendant, worth around 32000 altogether.

Hidden Conversation With Hunnigan:
Near the church in Chapter 1-3, instead of going up to the church, take the path towards the lake. This will trigger a conversation with Hunnigan, where Leon stumbles with words.

Help during 2nd Boss fight:
At the start of the game you'll find a dog stuck in a bear trap. If you go over and free it from the trap it will help you later during the second boss fight.

Speedy Pitch Aim:
Use the D-pad in conjunction with the Analog to swiftly aim up or down at 2x the rate. Great for knifing or quick point-blank grenades.

How to avoid the first battle with Krauser in the fortress:
When you enter the fortress and trigger the conversation with Krauser, immediately run forward to the shack with the locked door. Examine the door and the light will switch to red.

It will take a few minutes before the door automatically unlocks. Smash the boxes on both floors for items.

Meanwhle, Krauser will come to hunt you down. However, you can avoid the battle completely! Instead of wasting ammo and losing health to confront him until he uses the flash grenade, simply climb the ladder up and down! Krauser cannot hurt you when you climb the ladder!

Repeat the ladder climbing process until the door unlocks!

Extra Colored Eyes treasures:
Before you enter the clocktower section, if you destroy the Novistador nest, a lot of Red / Blue / Green Eye treasures will be dropped.

Choose the color of gems dropped by novistadors:
A novistador's eyes will change color every few seconds, they also stay in certain colors more than others. This is why green gems are most common, red gems are less so and blue gems are infuriatingly rare. The color gem that is dropped is determined by what color the novistador's eyse were when it received the killer blow. It can still be very tough to wait for a certain color when you're being charged but this does come in handy for finding all three colors necessary for a butterfly lamp.

Extra ammo:
When in the cabin with Luis (and Ashley), fighting the Ganados coming through the windows, stand by Luis. If you stand near him for long enough, he will start throwing handgun ammo to you.

Krauser's Secret Weaknesss:
Normally, The knife is a last ditch, limited range, very weak weapon, Dealing less than 5/8 the damage of an unupgraded handgun. In the timed fight versus krauser, If you knife him in the head it deals about 40x the damage that it would normally inflict. It saves ammo, and is as strong as a powerful magnum.

Detect Cloaked Parasites:
When you walk into a room you suspect the parasite things inhabit. Use the laser and move it around the room. It will glow brighter if one is there.

How to make the Gatling Gun appear without allowing the red monk to use it:
In the castle, there is a glitch where you can make the Gatling Gun appear without allowing the red monk to operate it.

First, progress normally and let the red monk escape. Once you return to the turret room, he will be operating the gatling gun. Immediate leave the room and return to the main hall with the merchant and save.

Load the game and re-enter the turret room. You need to chase the red monk again until he returns to the turret room. When you return to the turret room, the turret will be raised, but the red monk will be standing outside of the turret ring! Without the turret on his side, finish him with ease!

Quickly reload your weapon:
Whenever you have the chance to dodge (A and B, or L and R), if you are in the middle of a reload (Or just started one), and you perform the dodge, after you dodge your weapon you will have a full clip of ammo, as if you fully reloaded it. Useful for fighting bosses where you don\'t have a lot of time, or when you must reload an item that would normally take awhile (Such as the Broken Butterfly).

Float on air:
This glitch can be tried in places where you have to catch Ashley from a high drop, or an obstructing object.

After rescuing Ashley, head for the first Village you come accross.Take both Leon and Ashley up the tallest building, and tell Ashley to wait, and have Leon jump down by himself.

Call Ashley again and look for the prompt to "Catch" her. Have Leon move as far back out of the building's archway, just enough so that he is outside but the "Catch" prompt is still there.

Catch Ashley. The camera will have trouble adjusting to following her. When both her and Leon are standing normally, both of them will be hovering 6 feet off of the ground.

You can now run around the Village above the ground, until you try to leave (the path with the beartraps), and then fall back down again.

Instant KO against gatling gun Ganados:
When you get to the second wave of enemies when Mike is helping you, destroy the guns with the Infinite Rocket Launcher BEFORE you enter that area. Once you go past the shutters, the Ganados will rush to their posts, but only to die immediately. It will also work with the regular Rocket Launcher, but that only has one shot, so... yeah.

Cage Match Made Easy:
Having trouble beating the Garrador in the cage? All you have to do is press start during the cut scene before he jumps down and you will be left in the cage with only two monks.

100% hit rate with Infinite Rocket Launcher:
To do this, you need at least one normal weapon, and the Infinite Rocket Launcer.

At the begining of each chapter hit an enemy with any weapon once (any weapon other than the IRL) You can then fire away at anything with the Rocket Lancher, no matter if you hit or miss an enemy, and you will get 100% hit rate at the end of the chapter. This happens because the game does not register the Rocket Launcher hits like the other weapons hits.
