Total size when I play this game is 338 MB. Search and hunt zombies in first person view. In the lobby there is a radio to listen to music, 3 types of music are available. There is an increase in health points and regeneration. There is a selection and purchase of weapons, There are 2 types, melle and fire arm. There is a mission map to start the game. As for the next room, there is a computer to play Dota (😂 LOL). The fridge contains buff. and bass to play by default.
As long as you don't access the boss room, the waves of zombies will continue to run. The most effective way is to destroy their heads. Will get points for every zombie defeated, points are used to improve movement ability, regeneration, weapons and add ammunition.
To access the upgrade place need points, find the button in every corner. After activation, stairs leading to the basement will appear. Look for the floppy disk to access the boss room and look for the weapon upgrade room, the room is like a lab with the word "upgrade" written on it. And for movement and health upgrades, it looks like a vending machine.
Don't be surprised because a short advertisement will appear when starting the game and after completing the game. There are no annoying ads in the middle of the game.
To buy weapons, just play some games to get crystals. These crystals are then used to buy weapons and improve abilities.
Thanks and see you next game...
