Intricate, animated and hard-to-see details like these are just one of the many reasons why I’m fond of the ‘Meet the Team’ trailer series from TF2.
In his own trailer, the Sniper takes out a bullet, then twirls it around his fingers before reloading his rifle and pushing the bolt forward (in less than 2 seconds!),
I made a GIF of the scene, except it’s taken in slow motion.
Apparently in the game, he does the same action too if you look hard enough.
also, you’re welcome to use this, since I’m going to be using this as an animation reference!
