All who mock the PARA shall die horrid deaths. Like being shot with an UMP 400 times for 20 dmg.
The Para is all about fun and ridiculousness, all in a neat little bullet spraying package. Don't try to spray with it, even with 100 rounds in the box mag, it won't hit a thing because the recoil is horrible. Shoot it like any other gun in the game.
A good thing to do is to use the para like a shotgun. Pick up a D. Eagle for long range, and deal with anything else with the para. It's more suited for maps like Office where there aren't crazy long distances that you can't cover easily with the gun.
