Menu selection
Engineer and Rocket Launcher holds their weapons as if it's a rifle on the selection menu. It looks funny in the latter's case, since the bazooka seemed to be floating above the soldier's hand
Sprint
In First Person Mode
You can cancel animations of weapon reload, but not the reloading itself, and you seemed to be able to reload while sprinting, and the animation went to normal walk after that, then blinked a bit when you finished sprinting
Also, if you sprint to ladder, you still looked like you're sprinting even though you're already climbing.
