This might be patched out by the time you’re reading it, but currently there’s an annoying little issue when looting a corpse. Ammo and explosives are added to your inventory as you hold down the loot key, and there’s no animation. Let the looting progress bar fill up, though, and suddenly you jump into a disorienting hand grabbing motion before being allowed to stand up. If you stop pressing the key after the loot is collected but before the bar finishes, however, you can skip that animation all together and get back to cover. It’s a minor thing, but it does make a difference when you’re being shot at, so it’s worth getting used to ‘active looting.’
