Numpad 1: Unlimited Health - toggle on and most things cannot kill you.

Numpad 2: Unlimited Ammo/Items - toggle on and most items when used or most weapons when you reload, you have unlimited amounts. Probably best to leave this off until you reach the part of the story where you must create a Molotov cocktail, as that part of the game requires you to pick up items to make it and you cannot do so if this is on.

Numpad 3: No Reload - toggle this on and you can fire most weapons without reloading.

Numpad 4: Mega Credits - toggle on and press the middle mouse button to see you have more while in the game.

Numpad 5: 99 Resources - toggle on and press the middle mouse button to see you have more while in the game. Probably best to leave this off until you reach the part of the story where you must create a Molotov cocktail, as that part of the game requires you to pick up items to make it and you cannot do so if this is on.

Numpad 6: Hack Timer - toggle on and some of the hack locations that have a timer will freeze the timer.

Numpad 7: Unlock All Items - toggle this on and when you enter a SHOP you can buy all the weapons, addons, etc. You still need to UNLOCK them by purchasing before you can buy more of them.
