# Play as any unit with a pinned grenade
# Equip any grenade with a pin
# Prepare to throw grenade (unpin) by holding [LMB], then repin with [R]
# Observe pinning animation twice, and missing pin after "repin"
# Put away the pinless grenade or drop it
# The grenade will be pinless if you pull it out again or observe it dropped on the ground.
# Picking up the pinless grenade will not give its pin back.
# Throwing a different grenade will not bring the pinless grenade's pin back.
