EA and Crytek are taking a slightly different approach in their "Multiplayer Progression" series, showing us exactly how multiplayer works in documentary form. "Part 1: The Nanosuit" covered -- you guessed it -- Nanosuit progression and the various upgrades you can attach to it.
Today, we get the second part to the series, simply titled "Weapons." If you find the base selection of firearms lacking, rest assured you can pimp it out to your heart's content, given time and dedication. Like the Nanosuit, weapons can be upgraded the more you play and unlock.
Don't resist the urge to accessorize -- it's only natural. Of course, once you're no longer satisfied with the standard upgrades (i.e. scope, laser sight), you can step into the realm of more exotic mods.
