Unlock everything easily!
Well someone was bound to do it…
The memory address that contains the CoD4 XP has been located, and you can now modify it, making leveling up a much faster and easier process. This means that you can easily get the Commander Rank within a few hours of buying the game, and you can unlock all perks and weapons.
The memory address needed is: CBF0E68
You can use a tool such as Tsearch to edit the value of that address (your XP), so that you’ll only need one XP to get to the new CoD 4 rank.
Here’s how: open Tsearch, start a new script, enter the memory address, then enter in the XP you would like. Keep in mind – you’ll want to back up your Call of Duty 4 profile just in case something goes wrong – YOU HAVE BEEN WARNED! They also give you tips on what not to do which can prevent you from losing all of your saved data.
More details: if you just want to quickly go up a level, take your current XP from the Rank screen in the multiplayer mode, then add the amount of XP you will need to go up a level. You’ll want to subtract one or two XP in order to make it easy to gain a level. Then, go online and kill someone, or get an assist – BAM! – instant level up, and possibly a new rank.
Overkill perk, here you come!
Seriously, though, I tested this method, and found it much more enjoyable to play through multiplayer the real way – it’s more of a challenge, and fun!
