13. Nosalis (Metro 2033)

Leaping and screaming their way into number 13 is the mutated mole abomination only known as the nosalis.

These scary monsters will commonly attack you throughout each level of metro 2033. Nosalis are generally portrayed with large claws, arched spines and massive jaws filled with razor sharp teeth.

Being territorial pack hunters, these underground mole like monsters have reached terrifying sizes as a result of enormous amounts of radiation. Although weak individually, this weakness is made up for by the sheer numbers attacking players from every angle.

If a nuclear apocalypse ever does occur, be sure to bring lots of friends and even more bullets, because the nosalis will be waiting.
