When you successfully eliminate an enemy, you will automatically switch to the next weapon. In fact, with this automatic switching, sometimes when facing two or more enemies, one enemy is successfully killed, and then the next weapon is suddenly switched while strafing, and then nothing happens.

To put it simply, there are 18 weapons in total, and you need to use each one to eliminate an enemy to win in the end.
Let’s talk about weapons. Weapons are not fixed in each round. Each level is randomly assigned, but the weapon types at different stages are consistent.

For example, there are submachine guns at the beginning, then rifles, then continuous snipers, then single-shot snipers, then shotguns, then pistols, and finally fixed pans.
There should be 3 submachine guns, 4 rifles, 3 continuous snipers, 1 single-shot sniper, 3 shotguns, 3 pistols, and 1 pan. In total, there are 18 weapons.

This mode tests the player's all-round use of weapons, because you may need to use a pistol to face the enemy's rifle, and finally even a pan to face the enemy's weapon, so positioning is also particularly important.
