The corridor was narrow, holding the high ground gave them an absolute tactical advantage. By just guarding at the top of the stairs and firing down, the aliens below stood no chance of ascending.
When Natasha was alone, she barely managed, but as soon as Yuri, Shen Mo, and Ada all arrived, nearly all the attacking aliens were killed!
Gradually, more and more corpses piled up on the stairs, but the aliens still surged upward endlessly!
"Shit!" Ada cursed, "I'm almost out of ammo! How can there be so many!"
The rest were also running low on ammunition.
"Retreat!" Yuri threw a grenade, grabbed his gun, and started to fall back!
The rest evacuated as well, slamming the metal door of the fire escape shut with all their might!
A loud bang! The metal door trembled violently! However, after a few seconds of quiet, that howling resumed, more aliens rushed up the stairs, their frenzied banging against the metal door resonated with repeated thuds!
