The new update to our survival game is all about a giant mutated serpent! The virus has spread all over the world, and it's now threatening our sanctuary.

The virus has turned almost all of humanity into zombies. It's your mission to fight against the giant mutated serpent.

In the new update, we've added new challenges to the game. You have to fight the giant mutated serpent, which is even larger than before! That means you have to use all of your firepower to destroy it.

As you fight, you will earn points that you can use to unlock new weapons. Your weapons and armor will improve as you fight. You can also earn rewards by killing enemies and using items.
