Easy Intel:
-----------
The following works on the mission entitled "Hunted". After fighting your
way through a basement (after going underneath a bridge, across a field,
et cetera), you'll reemerge outside. A nearby house next to a vending
machine and a car should be your target from here. Inside the house,
there's a laptop on the table. This is a piece of Intel, and collecting
all thirty of them in the game will unlock all of the Cheat options available.
If you collect the Laptop, and then head through the nearby checkpoint, it
will be permanently acquired on your save file. Kill yourself at this point
(a Grenade is an easy way to do so), and backtrack to the house. Collect
the Laptop again, go to the checkpoint, kill yourself, and repeat the
process. By doing this, you can collect thirty laptops without actually
collecting all thirty of them.
Prestige Mode:
--------------
To unlock Prestige Mode, which is a multiplayer-only mode, you must reach
experience level fifty-five. Instead of capping out at level fifty-five,
which is the highest level, Prestige Mode allows you to start again from
level one. This can be done a total of ten times, giving you ten different
icons in in-game lobbies to show your extreme achievement.
