将 main/iw_11.iwd 的档案用winrar 打开, 可以见到各种武器的真实数据 (游戏内的数据假的)
Here are some numbers straight out of main/iw_11.iwd

每把武器瞄准的时候会变得无限准, 枪附带的准星顶点就是子弹的着点
Every weapon (sans shotguns) has perfect 0 spread when sighted. Tip of the sight is where the bullet will go.

突击步枪 - 全部射程皆有 1500-2000. 当加上灭声器的时候, 射程缩短至750-1500
当距离超过1500 时候, (子弹)攻击力会跌至第二个数字并继续飞行
ASSAULT - All have a range of 1500-2000. When silenced, the range becomes 750-1500.
After 1500 range, damage gradually drops to the second number and continues on after 2000 at that lower value.

M16
DMG: 40 - 30 | ROF: .065 (925~ rounds per minute)
