Armored Core

Playstation

Emblem Background:
Create an Emblem and go to the 'Edit Emblem' screen, and press L1+R1+L2+R2+Select. It should now be set as your new background wallpaper.

Fire the Lazer Blade:
You can fire a beam of light from your lazerblade. To do this, hit O to use the lazerblade, then as the arm comes down hit X. It has no lock so you really need to have good aim. If done correctly it will fire a crescent shaped beam. This cheat only works after you have enabled the 4th death advantage, firing back weapon while moving (see below).

Unlimited EP, Leg WP and Core WP:
Once you complete 100 missions, the game will automatically give you unlimited leg weight points, core weight points, and generator output points. So now the only limit will be your cash.

Cockpit Mode:
When playing, press Start+Square+Triangle to switch to cockpit mode.

Camera Mode:
While playing press Start+Circle+X at the same time. The camera will stay where it is while you move. Hard to play like this, but fun!

Free Money:
First find a mission that pays you in advance. Then go into the mission but quit right after the mission starts. If you did it right you get the advance money without doing anything!

Advantages of Death:
If your debt falls below 50,000 you start the game over with all your items and a special ability...

1st time: grid radar
2nd time: nothing
3rd time: radar missile display
4th time: fire back weapon while moving
5th time: nothing
6th time: double booster power

Secret weapons and parts can be found in certain stages:

Large rocket launcher:
Found on the "Eliminate Strikers" stage that takes place on the bridge. At the start of the mission turn directly around and there are 3 vehicles and a makeshift roadblock. Destroy the vehicle in the middle to obtain the next to worse weapon in the game.
Head :
Found in "Guard Train" stage that takes place in the desert. Found in the grey box lying close to the tracks. If you can't find it just blow up all the boxes. It's not worth having and you will probably feel stupid for wasting ammo finding it.
Radar:
Found in "Guard Wharf Warehouse" stage that takes place conveniently at a wharf. The building directly behind your starting point contains the radar. Blow open the doors and take it. You will lose the mission but the radar is pretty good.
Laser sword:
Found in the "Kill Struggle Leader" stage in the wannabe ancient aztec temple. The second hallway you come across that flings those flaming bowling balls at you has a hollow floor. If you check your map you can see it. Shoot up the floor and fall all the way to the bottom. It's at one end or the other. Enjoy getting out of the hole. The laser sword is far better than the other three. A must have if you use laser swords.
FCS:
Found in "Exterminate Organisms" set in the caves. When you get to the queen's chamber the FCS is a little odd colored spec on the ground next to the wall opposite the entrance. It may take a while to pick it up so for stress sake don't take a laser sword with you on this mission. It is the better of the "Wide and Shallow" series of FCS's. Can achieve one more lock on. Hey, take what you can get.
Flamethrower:
Found in "Destroy intruders" stage set in the blast furnace. Drop down about three or four levels and underneath one of the centered bridges will be a niche in the wall containing the flamethrower. The niche itself does not show up on the map but the box shows up enough to where it looks like a pixellation problem on the map. This is the worse weapon in the game.
Boosters:
Found in "Guard Secret Entrance" stage set in the open at night. In the northeast corner of the mission area their is a box just over a hill. Its at the very edge... don't go to far. Very nice boosters with extremely low weight, good boost, and average energy consumption.
Small missile launcher:
Found in "Secret Factory Recon" stage set in the aforementioned open night. In the very southwest corner of the mission area just over a hill is another box on the very edge containing a very nice small missile launcher. This one is great. It fires up to four missiles at a time and fires straight for use in tight quarters instead of at an angle like the six shooter pod.
Laser Rifle:
Found in "Destroy Fuel Depot" stage set in the... well, fuel depot. In the very back room on top of the ledge on the left hand side. It's a huge laser rifle that has great range and does awesome damage. It only has fifty shots though. This is the premier anti AC weapon to own (unless you can't seem to hit anything).
Dual missile launcher:
Found in "Retake Aircleaner" stage set in well... uhhh, a really big air cleaner. Found in one of the passages in the ceiling of the main chamber. This is the mother of all missile launchers. The name is certainly misleading. Dual implies two while this demonic contraption launches 6 missiles. Kills damn near everything in one volley. It works best if you are in the air when you fire it, or if the target is in the air.
Generator:
Did you not go on the "Kill plus escapee" stage? Wasn't good enough money? Think again... the best generator in the game is located in this mission. It's a small mission board - Ray Charles could find this one.
