Headcrab

Headcrab
The Headcrab is an enemy in Xibalba. Its appearance is a yellow, carnivorous alien. It bears a striking resemblance to the fictional alien parasitoid from the Half-Life series with the same name.

This small enemy will, once you have entered the radius, move towards you and once it is close enough, fly towards you with mouth open and inflict damage.

It shares the same or similar small health pool with the Sentry, taking 1 hit from the Shotgun or the Rocket Launcher, and a few seconds firing from the Rapid Laser.
