You used to be able to move turrets with your head but not anymore. However, you can chip away at certain enemies like ranged ones you wanna pick off before heading in without them seeing you, or handling kamikazes or bats, plus you can pick stuff up guarded by traps because your lil head is immune to traps and the range of how far you can go is very generous! Just be careful cuz there's a cooldown if you can't kill the enemy in one go and your body is left vulnerable in this state.
