Numpad 2: Unlimited Ammo - toggle on and most weapons will have unlimited ammo.
Numpad 3: Grenades/Molotovs/Ammo - toggle on and some weapons, molotovs, and some other items will have plenty. Please note that for some items, you may have to have at least ONE of them for this to give you plenty.
Numpad 4: No Reload - toggle on and when you shoot you will not need to reload most weapons.
Numpad 5: Invisible - toggle on and most enemies and police and etc. have no idea you are near them. You can escape, or shoot people point blank with no repercussions.
Numpad 6: Indestructable Car - toggle on and most vehicles you drive will be indestructable. There may be some slight superficial damage but normal catastrophic damage is avoided. You can use this to drive around town wildly without fear.
Numpad 7: Unlimited Sprint - toggle on and you can sprint indefinitely.
Numpad 8: Unlimited Adrenaline Shots - toggle on and when you use shots you will have more.
Numpad 9: Add Cash Wallet - each press adds more.
Numpad 0: Add Cash Stash - each press adds more.
Numpad /: 99 Wiretap Electronics - NEW! Use as directed! To use this, press ESC to open the map, note your wiretap electronics value at the lower right. Press this key. Leave the MAP and then come back and you will see you have more. The value shown on the HUD in the action portion of the game may not reflect this new value until you save and load or until you spend wiretap electronics.
Numpad *: Teleport to Waypoint - instructions are important! This option will ONLY work if you are on FOOT! Secondly, this option is only for teleporting a certain distance, NOT ACROSS THE ENTIRE MAP. You can teleport roughly about one district over (for instance, when you mouse over a section of the map, an entire DISTRICT lights up slightly. If you teleport farther than the game has calculated, your teleport will fail and your character will seem to be stuck. Experiment a few times to get a grasp on how far you can teleport. This DEFINITELY makes the game MUCH FASTER, as you can move around an area (like THE HOLLOW) to the various points of interest almost instantly! First, press ESC key to open the MAP. Next, left click on a location on the map so that the little white marker that looks like a solid white shield is on the map. You CAN click anywhere, but probably roads work best. Next press ESC to leave the MAP where you can see your character. Then press the option key and you will teleport to the location instantly! You can teleport once every 6 seconds or so. You can move quite a ways very quickly and this keeps you from having to run or get into vehicles and drive back and forth.
