Looking for a general weapons guide? Check this one out. Or is a guide to single player mode more to your liking? Or perhaps you just want to know how the game stacks up? Check out this review.

Marathon

Marathon as a perk lets you run endlessly. This is great for mobility on any class, as having to pause when you're retreating can get you killed, and having to stop and start when rushing to the action can leave you late to the party. The pro version of the perk allows you to climb over objects faster than normal, which leads to taking cover much quicker. The challenges are easy to complete, they just take time. Run everywhere, all the time.

Marathon Pro I: Run 1 mile with Marathon. Unlocks the Trackstar title. Worth 500 EXP.

Marathon Pro II: Run 5 miles with Marathon. Worth 1,000 EXP.

Marathon Pro III: Run 10 miles with Marathon. Worth 2,500 EXP.

Marathon Pro IV: Run 26 miles with Marathon. Unlocks the Marathon Pro Perk. Worth 5,000 EXP.

Marathon Pro V: Run 52 miles with Marathon. Unlocks the Freerunner title. Worth 10,000 EXP.

Marathon Pro VI: Run 104 miles with Marathon. Unlocks the Decathlete title and the Marathon Pro Emblem. Worth 10,000 EXP.

Scavenger

Scavenger as a perk allows you to pick up small blue ammo resupply packs from fallen players. These packs will refill your ammo, grenades, and equipment. The pro version of the perk has a similar effect as the Extended Mags attachments, granting you additional ammo when you start. This perk is also easy to complete challenges for; you can pick up ammo packs any time, so long as you have fired a shot.

Scavenger Pro I: Pick up 10 resupply packs. Unlocks the Reloaded title. Worth 500 EXP.

Scavenger Pro II: Pick up 25 resupply packs. Worth 1,000 EXP.

Scavenger Pro III: Pick up 50 resupply packs. Worth 2,500 EXP.

Scavenger Pro IV: Pick up 100 resupply packs. Unlocks the Scavenger Pro Perk. Worth 5,000 EXP.

Scavenger Pro V: Pick up 250 resupply packs. Unlocks the Bandolier title. Worth 10,000 EXP.

Scavenger Pro VI: Pick up 500 resupply packs. Unlocks the Vulture title and the Scavenger Pro Emblem. Worth 10,000 EXP.

Bling

Bling allows you to have two attachments on your primary weapon instead of just one. This is excellent for using silencers and sights together, or heartbeat sensors with FMJ rounds, or any other combination to make your weapons more effective. The pro version of the perk allows you to have two attachments for your secondary weapon as well, useful for certain shotguns and machine pistols. Useless for launchers, however. These challenges are easy to complete; simply kill players with weapons that have two attachments.

Bling Pro I: Kill 25 players using two attachments. Unlocks the Double Down title. Worth 500 EXP.

Bling Pro II: Kill 50 players using two attachments. Worth 1,000 EXP.

Bling Pro III: Kill 100 players using two attachments. Worth 2,500 EXP.

Bling Pro IV: Kill 200 players using two attachments. Unlocks the Bling Pro Perk. Worth 5,000 EXP.

Bling Pro V: Kill 450 players using two attachments. Unlocks the Bling Bling title. Worth 10,000 EXP.

Bling Pro VI: Kill 900 players using two attachments. Unlocks the Armed and Dangerous title and the Bling Pro Emblem. Worth 10,000 EXP.
