25 Most Annoying Video Game Enemies

POISON HEADCRABS (HALF-LIFE 2)

Another obvious choice for a list like this. Poison Headcrabs can be found in abundance in Half-Life 2, and they’re never exactly easy to deal with. They’ll latch on to your head and bring you to within an inch of death, and their agile movement means that there’s always a high chance of wasted ammo. They might not be the biggest or most durable foes you fight in the game, but boy are they a big threat.
