Wasteland Survival: From the Start, I Get the Shadow Sniper Rifle as a Sign-In Reward

The main character's operation is too confusing to understand. First of all, the main character has a sniper rifle, which can sneak attack and kill monsters from a distance. But he doesn't use it. The monsters don't move and they don't even shoot when they are resting. Instead, they hit the objects next to the monsters to wake them up and steal the treasure chest to escape. You can say that you are confused or not. Can't you just kill them and then take the treasure chest? The second protagonist has been upgraded to two levels, and there are various long-range weapons such as sniper rifles, bows, and crossbows. Their numerically crushing existence can make little Karami escape, or he can escape by running with his legs. The third one suddenly cared about helping a woman. I only made a transaction once, but it was an online transaction, so I hurriedly went to save her. After I saved her, I couldn't forget her. I'm so speechless.
