Replaces the simple zoom for weapons without scopes with full iron sights. It doesn't simply use an image, the front and back sight actually line up in the center of the screen over the crosshair. There is a new option to remove the crosshair.
The next iteration. A number of new features have been added, some smaller, some larger. (But it's OLD now!)
Alpha 1.1 improves upon alpha 1.0 by fixing a few glitches and adding a number of features.
The most noticeable additions are as follows:
The only remaining actual glitch (that I know of) is that the weapons vibrate just slightly when sighted in. I have tracked this glitch down to the very core of the engine, and to put it shortly, unless I had an animator, there is no way to fix it. Therefore, in order to keep it from being distracting none of the sights are held directly up to the player's view. It's still slightly noticeable, but it is much subtler than before.
