Metal Gear Solid V: 20 Things You Didn't Know You Could Do

3. You Can Fulton The Skull Unit For Unique Items

The most annoying enemies in the game by a landslide, the infuriatingly agile Parasite Unit makes for some of the most frantically combat-heavy encounters in the entire game - not to mention if you do manage to overcome them or escape, Fulton'ing will be the last thing on your mind. However, you'll need to bring them back to Mother Base to develop the various buffs necessary to unlock some late-game armour abilities. To say more would be spoiler territory, but sufficed to say they can actually be a huge help to Snake's missions if you know what you're doing. Either continually plug away at them with stun grenades, sleeping gas or rubber bullets, or providing you haven't killed the 'leader' (who has more health than the rest), you can use lethal weapons instead. Until the leader is down, each Skull can be Fulton'd out when they're lying on the ground - just make sure you've upgraded your Fulton equipment to at least the second level.
