The surprising thing is the degree to which the animations have been done. Pick up a 1911, for instance, and you'll find a perfect example of the typically exceptional attention to detail displayed throughout the mod. If you empty the magazine and have the slide lock back, upon holstering it you'll see that your character releases the slide before holstering it - just like anyone would do in reality, since you don't holster a slidelocked pistol. It gets better than that, however - draw the pistol once more and the slide will be forward on an empty chamber and empty magazine. Pull the trigger and the hammer will drop on the empty chamber, after which your character's thumb will cock it back again. Reload at this point and your character will drop the empty magazine, insert a new one, and then manually pull the slide to the rear before releasing it to chamber a new round. That Infiltration has dedicated animations for something like this, when almost as a rule all other games miss such details, is once again testament to the incredible attention to detail displayed by the team.
As in the prior tactical gaming effort, the article is illustrated with plenty of screenshots and videos.
