All Weapons
The first Tomb Raider is an action/adventure game. You control Lara Croft and must complete mission-based levels with the use of wits and weapons. When you first begin, your weapon cache is very small and rudimentary, but grows as you proceed through the game. Cheat codes come in handy for those who either do not want to wait, or are having trouble getting that one special weapon they desire. To cheat, hit "Select," then go to your inventory screen. Once there, input ̶0;L1, Triangle, L2, R2, R2, L2, Circle, L1̶1;. If done correctly, Lara will sigh. Then hit ̶0;x̶1; and return to your inventory screen to access every weapon in the game.
Invincibility
If you are tired of losing health during combat, or simply do not like to worry about dying, this cheat code is just what the doctor ordered. Pause the game and enter ̶0;Triangle, Square, R1, L2, Circle, and Square.̶1; If done correctly, Lara will become invincible, which should make your progress through the game much easier.
Level Skip
If you want to advance to the next level without playing through the current level, or if you are stuck and just want to get past the current challenge, go to the inventory screen, just as you did in Step 1, and enter ̶0;L2, R2, Triangle, L1, L1, Circle, R2, L2, Select̶1; and you will jump to the beginning of the next level.
Grenades
If blowing things up is more your style, then you will go through a lot of grenades. To reload, go to the inventory screen and enter ̶0;L1, L1, L1, L1, L2, L2, Circle, Square, Square, Triangle, Triangle.̶1; You should hear a moan to confirm you entered the code correctly. Now you can continue to blow things up at will.
Reload
If you run out of ammunition, enter the inventory mode and enter ̶0;L1, Triangle, R2, L2, L2, R2, Circle, L1̶1;. Lara will let out a sigh, just as she did with Step 1, and you will be ready to lock and load.
