You find yourself trapped in a dark sewer, surrounded by deadly water and even deadlier aliens. What makes this even worse is that your flashlight is running out of battery! The only way to recharge it is by dealing damage and killing as many aliens as you can while you make your way through the underground. Find the right balance between recharging your flashlight and collecting as many weapon crates as possible.
Weapon crates will spawn randomly during your hunt. As you collect crates you score points and switch to new random weapons, which makes the task of killing aliens quite varied, difficult and addicting. There are currently 30+ weapons waiting to be unlocked.
