The best Modern Warfare 2 perks and perk system look slightly unfamiliar this time around, with new perk packages entering the fray. Perk packages still include two standard perks, but bonus and ultimate perks make their debut in the FPS game.
Perks are just one part of your Modern Warfare 2 multiplayer setup, and allow you to choose a loadout of four, each with its own unique benefit in the multiplayer game. These could be hiding you from enemy UAVs or spawning with an additional tactical item – and the right perk could make the world of difference to your performance.

Bonus and ultimate perks explained
While we're used to having perks that are active from the very start of a game, and basic perks still are, bonus and ultimate perks work slightly differently, only becoming active part way through the game. As standard, bonus perks are earned four minutes into each Modern Warfare 2 multiplayer match, while ultimate perks become active after eight minutes. This time can then be reduced by killing enemies and capturing and holding objectives.
Each time you respawn, perk icons show at the bottom of your screen, showing how close you are to activating your bonus and ultimate perks. Once earned, you'll get a large visual notification, and audio confirmation.
Perk packages
A perk package quite simply is the umbrella term for your setup of two basic perks, one bonus, and one ultimate. There are some preset perk packages to choose from if you're not sure, or you want to give some new perks a try. Even better, once you manage to work out your favourite perk loadouts for each different mode, you can save them all, and uniquely name each package.
That's everything we know about Modern Warfare 2 perks. While you wait, why not familiarise yourself with all the game modes in which the perks above will be so crucial.
