As targets for those who like to shoot in the gaming space, the most popular are zombies. In the game A Zombie Survival, your hero has to go through an underground bunker and smoke out all the ghouls from there. They roam the corridors and hid in separate rooms. Find everyone and shoot them. To feel more confident, go through the training level. On it, you will understand the capabilities of the character and the perceived threats. In almost every room you will find stocks of weapons and you can change them like gloves. Do it not just like that, but wisely, because weapons have different effectiveness in A Zombie Survival.
