I always wondered why people shouted "speedhacker" at me so much. I have a feeling most people ignore there's two pages to the helmets/hats section.
The Combat Beanie increases speed by 3%, the Bandana increases by 5%. Combined with light armor which increases by 10% and a sub machine gun...
You're running at 18% faster speed. While that doesn't seem like much, it's enough so that a person [like me] whose finger hovers over the sprint function, and knows the map quite well, can evacuate the premises of a firefight in short order when it gets out of control.
One of the reasons I don't like Death Room or Junk Flea. When the shit hits the fan and the engagement isn't in my favor, I don't have dodging room. I just have to pray I can outshoot the five guys that walked out of their spawn.
With invincibility.
